Amorphous (4R-cis) -6- 2- 3-phenyl-4- (phenylcarbamoyl) -2- (4-fluorophenyl) -5- (1-methylethyl) -pyrrol-1-yl -Ethyl -2,2-dimethyl- 1,3 -dioxan-4-yl-acetic acid

摘要

The invention relates to a process of preparing amorphous (4R-cis)-6-[2-[3-phenyl-4-(phenylcarbamoyl)-2-(4-fluorophenyl)-5-(1-methylethyl)-pyrrol-1-yl]-ethyl]-2,2-dimethyl-[1,3]-dioxane-4-yl-acetic acid-tertiary butyl ester which is a useful pharmaceutical intermediate in the preparation of atorvastatin salts.
