To prepare 6-methyl-2- (4-methylbenzyl) pyridino [1,2-a] pyrimidine-3-acetic acid, there are many methods for synthesis, each with its advantages and disadvantages. The following are several common methods:
** First, take halogenated pyridine and pyrimidine derivatives as starting materials **
Take appropriate halogenated pyridine, such as 6-methyl-2-halogenated pyridine, and pyrimidine derivatives containing 4-methylbenzyl, in the presence of suitable bases and catalysts, carry out nucleophilic substitution reactions. Commonly used bases include potassium carbonate, sodium carbonate, etc., catalysts such as cuprous iodide and corresponding ligands. This reaction requires strict control of reaction temperature and time to ensure product selectivity and yield.
The reaction formula is roughly as follows: 6-methyl-2-halopyridine + (4-methylbenzyl) pyrimidine derivative $\ xrightarrow [catalyst] {base} $6-methyl-2 - (4-methylbenzyl) pyridino [1,2 - a] pyrimidine-3 -acetic acid
** Second, through heterocyclic construction strategy **
Using methyl-containing pyridine derivatives and 4-methylbenzyl-containing nitriles or amides as raw materials, the target product is synthesized through multi-step cyclization. First, the pyridine derivatives react with nitriles or amides under acidic or basic conditions to form key intermediates. After that, the intermediate undergoes intramolecular cyclization under the action of appropriate dehydrating agents or cyclization reagents to form a pyridyl pyrimidine ring system.
In this process, the conditions of each step of the reaction need to be carefully regulated, such as the type and dosage of acidic or basic catalysts, reaction temperature and time, etc., in order to optimize the reaction process and improve the purity and yield of the product.
** III. The coupling reaction catalyzed by transition metals **
With 6-methylpyridine-2-boronic acid or its esters and halogenated pyrimidine derivatives containing 4-methylbenzyl as substrates, the coupling reaction of Suzuki-Miyaura is carried out under the action of transition metal catalysts (such as palladium catalysts). This reaction is usually carried out under alkaline conditions, and the commonly used bases include cesium carbonate, potassium phosphate, etc. When
reacting, attention should be paid to the loading of the catalyst, the choice of the reaction solvent, and the deoxygenation operation of the reaction system, because these factors have a significant impact on the efficiency and selectivity of the reaction.
The above synthesis methods each have their own unique features. In practical application, the most suitable method should be selected based on the availability of raw materials, the difficulty of controlling reaction conditions, the purity and yield requirements of the product, and many other factors.

The physical and chemical properties of 4-methyl-2- (4-methylbenzyl) pyridino [1,2-a] pyrimidine-3-acetic acid are as follows:
From the perspective, this substance is often in a solid state. This is made by the intermolecular force, resulting in an orderly arrangement of molecules and a solid-state structure. Its melting point is quite important, because the value of the melting point can help to identify its purity and characteristics. However, the specific number of melting points needs to be measured according to precise experiments, including different production methods, purity and other factors.
When it comes to solubility, in common organic solvents, its solubility may vary. In organic solvents, such as methanol and ethanol, it may have a certain solubility. It can interact with polar solvent molecules, such as hydrogen bonding, dipole-dipole interaction, etc., and then it can be soluble. For non-polar organic solvents, such as n-hexane, benzene, etc., the solubility may be low, because the molecular polarity is different from that of non-polar solvents, and the intermolecular force is difficult to match, so it is not easily soluble.
Its chemical stability is also a key property. Under the influence of normal temperature and pressure, no special chemical reagents or conditions, it may have certain stability. In the case of strong acid, strong base environment, or because some groups in the molecular structure have reactivity, chemical reactions occur. Such as the nitrogen atom on the pyridine ring and the pyrimidine ring, or can react with the acid to form a salt; while the ester group or carboxyl group of the side chain can be hydrolyzed in the alkali solution.
And its spectral properties, such as infrared spectroscopy, can show the vibration absorption peaks of specific functional groups. The skeleton vibration of the pyrimidine ring and the pyrimidine ring, and the characteristic absorption peaks of methyl and benzyl groups, etc., can be presented in the spectrogram, which is helpful for the identification of the structure. Nuclear magnetic resonance spectroscopy can also provide information on hydrogen atoms or carbon atoms in different chemical environments in the molecule. The molecular structure can be inferred by the position of the peak and the split situation.
The physicochemical properties of 4-methyl-2- (4-methylbenzyl) pyridino [1,2-a] pyrimidine-3-acetic acid are of great significance in its synthesis, separation, purification and application, and researchers can make good use of them according to their properties.

What is the price of hexamethyl-2 - (4-methylbenzyl) pyridino [1,2-a] pyrimidine-3-acetic acid in the market today?
According to Guan Fu's "Tiangong Kaiwu", the price of a product often depends on various reasons. The first to bear the brunt is whether the raw materials are available. This hexamethyl-2 - (4-methylbenzyl) pyridino [1,2-a] pyrimidine-3-acetic acid, if the raw materials are dilute and difficult to recover, or if the collection is very laborious, the price will be high. For example, if the rare medicine in the deep mountains is difficult to find because it is not easy to find, and the price is high, it is difficult to find.
The second is related to the simplicity of the production method. If its production requires exquisite art, cumbersome process, and time-consuming, and requires skilled craftsmen and rare utensils, during which there are many people who spend manpower, material resources, and financial resources, the price will also rise. A wine that is good at brewing, after many processes and years of precipitation, can obtain a good wine, and its price is naturally not cheap.
Furthermore, the supply and demand of the city are very related. If this thing is needed by everyone in the city, and there are many people who want it and those who are in short supply, the price will rise; on the contrary, if the supply exceeds the demand, although the quality is good, the price will not be high. For example, if the clothes of the time are popular, the price will jump if the buyer wants them; the outdated models, even if they are skillfully crafted, are difficult to sell at high prices.
And the distance of the land and the amount of tax can affect its price. Produced in distant places, after long-distance transshipment, the fee must be added to the price; if the tax is heavy, the cost of the merchant will be high, and the price will have to rise.
However, I have not personally covered the market, nor have I carefully studied the current raw materials, production methods, supply and demand of this thing, so it is difficult to determine its price. To know the details, you need to visit the merchants of various pharmaceutical shops, or check the market conditions of the city, in order to obtain its exact price.

4-Ethyl-2- (4-ethylphenyl) pyridine, which is placed in the [1,2-a] position of acetamide to its -3-position, is crucial to the stability of its chemical properties and the shelf life. According to the principles of "Tiangong Kaiqi", each product has its own characteristics and exists in a way, so that it can have its own quality and extended use.
In terms of chemical preservation, the first priority is temperature. 4-Ethyl-2- (4-ethylphenyl) pyridine-3-acetamide, which is susceptible to molecular structure changes and activity changes when heated. Therefore, it is better to keep it in a cool place, so that the temperature is constant below 20 ° C. High temperature will intensify the thermal movement of molecules, or cause chemical bonds to break or rearrange, which will damage their chemical purity.
Humidity is also critical. If this substance is exposed to a high humidity environment, it is easy to absorb moisture. Water molecules intervene, or initiate a hydrolysis reaction, changing its chemical composition. It should be stored in a dry place. It can be assisted by a desiccant to keep its ambient humidity below 40% to prevent it from changing due to moisture.
Furthermore, light cannot be ignored. Light contains energy, or causes photochemical reactions of this chemical. 4-Ethyl-2 - (4-ethylphenyl) pyridine-3-acetamide is sensitive to light, and direct exposure to strong light will decompose or isomerize it. It must be stored in a light-proof container, such as a brown glass bottle, to prevent light from invading and keep its chemical properties stable.
In addition, this chemical may have certain volatility and reactivity, and must be sealed and stored. Sealing can prevent its volatilization and dissipation, and also prevent external air and impurities from reacting with it. After taking it, seal it in time to ensure its quality as before.
In general, the storage of 4-ethyl-2- (4-ethylphenyl) pyridine-3-acetamide requires temperature control, dehumidification, protection from light, and sealing. In this way, its chemical properties can be preserved for subsequent use, in accordance with the purpose of "Tiangong Kaiwu".
