Process for 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

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.
