To prepare 3 - (6 - (3 - cyanogen - 2 - fluorobenzyl) - 1 - [1 - (methoxy) - 2 - methylpropyl] - 7 - methoxy - 4 - oxo - 1,4 - dihydropyridine - 3 - carboxylic acid, the synthesis method is as follows:
First take an appropriate amount of compounds containing cyanide and fluorobenzyl groups, add appropriate catalysts and reaction aids in a specific reaction vessel, and carry out condensation reactions with reactants containing methoxy and methylpropyl groups at suitable temperatures and pressures. This step requires precise control of the reaction conditions. Due to high temperature or too long reaction time, side reactions can easily occur, which affects the purity and yield of the product.
After the condensation reaction is completed, the reaction mixture can be separated and purified. Extraction, column chromatography and other means can be used to remove unreacted raw materials, by-products and impurities to obtain relatively pure intermediate products.
Then, this intermediate product is combined with the reactant containing methoxy and oxidized dihydropyridine structures. In another reaction system, a specific base or acid is added as a catalyst, and the temperature and reaction time are adjusted again. Cyclization is carried out to construct the pyridine ring structure of the target product. This step is also demanding on the reaction conditions, and any parameter deviation may cause incomplete cyclization or the formation of other isomers.
After the cyclization reaction is completed, the product is separated, purified and refined again. Recrystallization, chromatographic separation and other technologies are used to further improve the purity of the product, and finally obtain high-purity 3- (6- (3-cyano- 2-fluorobenzyl) -1 - [1- (methoxy) -2 -methylpropyl] -7-methoxy-4-oxo-1,4-dihydropyridine-3-carboxylic acid. The whole synthesis process requires fine control of the reaction conditions at each step, and attention to separation and purification operations in order to achieve efficient and high-purity synthesis goals.

"Tiangong Kaiwu" says: "Seven flaxyl groups, four oxygen groups, one and four oxygen groups, and three carboxylic acids. What is the market prospect?"
