, (2018/09/08)
The invention belongs to the field of medical chemistry synthesis, and provides a preparation method of citric acid mosapride intermediate product IV 4-[(4-fluorophenyl)methyl]-2-morpholinemethanaminesalt and citric acid mosapride. The 2-(4-fluorobenzoamido)ethanol and 1H-Isoindole-1,3(2H)-dione,2-(2-oxiranylmethyl) are taken as raw materials, and the intermediate product IV 4-[(4-fluorophenyl)methyl]-2-morpholinemethanamine salt is obtained after acid treating is conducted; the intermediate product IV and an intermediate V 2-oxethyl-4-acetamido-5-Chlorobenzoic acid ethyl ester compounds aretaken as raw materials, dichloromethane is taken as a solvent, and EDCI and DMAP are taken as catalysts to prepare mosapride salt; the mosapride salt is reacted with citric acid aqueous solution to prepare citric acid mosapride. The intermediate product has the advantages that products are high in yield, raw materials are easy to obtain, the production cost is low, and the intermediate product issuitable for industrialized production.
