To prepare 5% 2C6-dimethoxy-2- (p-toluene-4-yl) methylene-naphthalene-1-one, the following ancient methods can be used to find the diameter.
First, the naphthalene-1-one is used as the starting material. First, it is mixed with an appropriate alkali agent to dissociate the α-hydrogen of naphthalene-1-one to form anion. After adding 5% 2C6-dimethoxy-2-halogen, the two can be obtained by nucleophilic substitution reaction to obtain 5% 2C6-dimethoxy-2-halomethylene-naphthalene-1-one. This halogen is then nucleophilic addition reaction with p-toluene-4-based metal reagents, such as Grignard reagent or lithium reagent, etc., to obtain the target product. When reacting, pay attention to the reaction temperature, reagent ratio and reaction time to prevent side reactions, such as excessive substitution.
Second, p-toluene-4-yl formaldehyde and 5% 2C6-dimethoxy-2-halogenated naphthalene-1-one are used as raw materials. In a weak base environment, the two perform hydroxyaldehyde condensation reaction. Under the catalysis of base, the carbonyl group of p-toluene-4-yl formaldehyde and the α-hydrogen of naphthalene-1-one generate carbon-carbon double bonds to obtain 5% 2C6-dimethoxy-2 - (p-toluene-4-yl) methylene-naphthalene-1-one. In this process, the strength and dosage of the base, as well as the properties of the reaction solvent, will affect the reaction rate and yield. Fine regulation is required to select mild weak bases, such as potassium carbonate or pyridine, and appropriate solvents, such as ethanol, dichloromethane, etc., to promote the anterograde reaction.
Third, consider using 5% 2C6-dimethoxy-2-naphthalene-1-one as a substrate, and first convert its carbonyl group to active intermediates such as enol ethers or enamines. Then let this intermediate react with p-toluene-4-yl halides under the catalysis of Lewis acid or transition metals for nucleophilic substitution or coupling. This path can increase the reaction selectivity and reduce side reactions. However, it is necessary to select suitable catalysts, such as aluminum trichloride, cuprous iodide, etc., and control the reaction conditions, such as temperature, time and proportion of reactants, to achieve the ideal yield and purity.

5% 2C6 -dimethoxy-2 - (p-toluene-4-yl) aminomethyl-pyrimidine-1-one, the price of this substance on the market is difficult to determine. The change in its price depends on various factors and cannot be generalized.
First, the price of raw materials has a deep impact. If the raw materials required for the preparation of this compound are scarce, or due to changes in weather, geography, and personnel, the output is reduced, or there are many people who want it, the price of raw materials will rise, and the cost of this compound will also rise accordingly. The price on the market will rise as the tide rises. < Br >
Second, the preparation method is also the key. If the preparation process is complicated, special equipment and exquisite skills are required, and there are a lot of losses in the process, the preparation cost will increase greatly, and the price will also be high. On the contrary, if the process is simple, the cost can be slightly reduced, and the price may be different.
Third, the market's demand determines the price. If this product is in high demand in medicine, chemical industry and other fields, and there are many people seeking it, but the supply is limited, the price will increase; if the demand is low and the supply exceeds the demand, the price may be downward.
Fourth, manufacturers and regions also have an impact. Different manufacturers, due to differences in technology, scale, management, different costs, and different pricing. And different regions, transportation costs, tax differences, etc., can cause price changes.
Therefore, in order to determine the exact price of 5% 2C6-dimethoxy-2- (p-toluene-4-yl) aminomethyl-pyrimidine-1-one in the market, it is necessary to study the raw material market, preparation process, market supply and demand, and the manufacturer's region and many other factors. In combination, a more accurate price can be obtained.

The storage conditions of 5% 2C6-dimethoxy-2- (p-toluene-4-yl) methylene-furan-1-one are the key factors for the chemical substance to maintain its chemical stability, ensure safe use and extend its shelf life.
The storage conditions are as follows: It should be stored in a cool and well-ventilated place. This is because high temperature can easily cause the substance to chemically react, and even cause decomposition or deterioration. If the storage environment temperature is too high, it may enhance the molecular activity and promote unnecessary reactions, which will affect the quality of the substance. Well-ventilated can avoid its accumulation in local spaces and prevent potential hazards caused by high concentrations. < Br >

Should be stored separately from oxidants, acids, bases, etc., and should not be mixed. Due to the chemical structure of the substance, it may react violently with the above-mentioned substances. If it comes into contact with an oxidizing agent, or initiates an oxidation reaction; encounters with acids or bases, or causes the structure of the substance to change due to acid-base reaction, losing its original properties.
Storage area should be equipped with suitable materials to contain leaks. In order to prevent the occurrence of leakage, it can be dealt with in a timely and effective manner to avoid the spread of leaked substances and cause greater harm to the environment and personnel. Materials such as cotton, sand and other materials can be prepared to quickly absorb leaked liquids and prevent their flow and penetration. Such storage conditions are to ensure the safety and stability of 5% 2C6-dimethoxy-2- (p-toluene-4-yl) methylene-furan-1-one during storage.
