Procedure

In a manner similar to the method described in Example 25a, rac-(2R,3S,4R,5S)-5-[1-(tert-butyl-dimethyl-silanyloxymethyl)-cyclobutylmethyl]-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 115b (0.7 g, 1 mmol) was reacted with trifluoroacetic acid in dichloromethane at room temperature to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(1-hydroxymethyl-cyclobutylmethyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a white solid (0.6 g, 100%).
