Product Description

Ezetimibe Intermediate 6 CAS number is 204589-80-0, Molecular formula C26H24FNO4, Molecular weight 433.47 ,Appearance is White crystalline powder.1-fluorobenzene and glutaric anhydride are subjected to Friedel-Crafts reaction under the action of the catalyst to give the compound 5- (4-fluorophenyl) -5-oxopentanoic acid,react with 1,3-propanediol to form the compound 4- (2- (4-fluorophenyl) -1,3-dioxan-2-yl) butanoic acid And then through four steps reaction to obtain the target product of ezetimibe intermediate 6. The difficulty in the synthesis of ezetimibe intermediate 6 is relatively big, with the fifth reaction involving low temperature reactions, which are difficult to operate for chemical plants in general terms. In addition, it is easy to produce a problem that the isomer content is too high. So the synthesis of ezetimibe intermediate 6 is definitely a test of equipment and technology.
