To prepare dimethyl 3 - (benzyloxy) - 1 - (2,2 - dimethoxyethyl) - 4 - oxo - 1,4 - dihydropyridine - 2,5 - dicarboxylate, the method is as follows:
First, the corresponding raw materials need to be prepared, such as compounds containing benzyloxy groups, reagents with dimethoxyethyl groups and related precursors of pyridine dicarboxylate. By classical organic synthesis, the raw materials containing active check points can be interacted first. Or first connect the benzyloxy group to the parent pyridine dicarboxylate. This step requires appropriate reaction conditions and catalysts, such as in an inert solvent and catalyzed by a base, so that the nucleophilic substitution or condensation reaction occurs between the two, so that the benzyloxy group is successfully connected to the 3 position of the pyridine dicarboxylate.
Then introduce a 1 - (2,2 - dimethoxyethyl) group. Nucleophiles can be used to react with 2,2 - dimethoxyethyl reagents containing halogenated or active ester groups. The reaction system may need to be controlled at temperature and time to ensure the selectivity and yield of the reaction. During this period, the properties of the solvent and the proportion of the reactants are all critical.
In the synthesis, the reaction process needs to be monitored by various analytical methods, such as thin layer chromatography, gas phase or liquid chromatography. After each step of the reaction, the pure product should be obtained by suitable separation and purification methods, such as column chromatography, recrystallization, etc. After multi-step reaction, separation and purification, the target product dimethyl 3- (benzyloxy) -1- (2,2-dimethoxyethyl) -4-oxo-1,4-dihydropyridine-2,5-dicarboxylic acid ester. However, the synthesis process is complicated, and the practical operation needs to follow the experimental procedures, and the reaction conditions should be fine-tuned according to the specific situation.

Dimethyl-3- (benzyloxy) -1- (2,2-dimethoxyethyl) -4-oxo-1,4-dihydropyridine-2,5-dicarboxylate, this compound has specific physical and chemical properties. Its appearance may be a crystalline powder, due to the presence of multiple functional groups in the molecule, resulting in this state of appearance.
From the perspective of solubility, due to its polar carboxylic acid ester group and dimethoxy group, it has a certain solubility in polar organic solvents such as methanol and ethanol, but it has little solubility in non-polar solvents such as n-hexane.
In terms of melting point, the exact value needs to be determined experimentally, but it can be speculated from similar structural compounds. Intramolecular hydrogen bonds interact with van der Waals forces, or the melting point is within a certain range. The intermolecular force is strong, so the melting point may not be extremely low.
In terms of stability, it is relatively stable under normal temperature, pressure and dry environment. However, in case of strong acids and alkalis, due to the presence of ester groups, hydrolysis is prone to occur. Under high temperature conditions, the molecular structure may undergo reactions such as rearrangement and decomposition.
Spectral properties also have characteristics. In the infrared spectrum, the vibration absorption peak of the C = O bond of the ester group may be in the region of 1700-1750 cm. In the H-NMR spectrum, hydrogen atoms in different chemical environments correspond to different chemical shifts, which can help to determine the environment and connection mode of hydrogen atoms in molecules, providing key information for structure analysis.

I don't know the price range of "Dimethyl 3- (benzyloxy) -1- (2,2 -dimethoxyethyl) -4 -oxo-1,4 -dihydropyridine-2,5 -dicarboxylate" on the market. This is a fine chemical substance, and its price is affected by many factors.
First, the price of the raw material is the main reason. If the various raw materials required for its synthesis are easily available and affordable, the cost of this compound may be reduced, and the price will be lower. If the raw materials are rare and difficult to find, or the preparation is complicated, the price will be high, resulting in a high price of the finished product.
Second, the preparation process is also cumbersome. If the synthesis method requires delicate steps, harsh conditions, or special instruments and reagents, the cost will increase, and the market price will be high; if the process is simple and mature, the cost is controllable, and the price is close to the people.
Third, the market supply and demand situation has a great impact. If the product is widely demanded in the fields of medicine, chemical industry, etc., but the supply is limited, the price will increase; if the demand is weak, the supply is abundant, and the price may decline.
Fourth, the manufacturer's brand and quality also affect the price. Well-known manufacturers, with high-quality products and reliable reputation, their products may be priced higher; new factories or unknown factories, the price may be lower to compete for the market. < Br >
