Procedure

In a manner similar to the method described in Example 25a, rac-(2R,3R,4R,5S)-3,5-bis-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 42a (0.45 g, 0.85 mmol) was reacted with trifluoroacetic acid in dichloromethane at room temperature to give rac-(2R,3R,4R,5S)-3,5-bis-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a off white solid (0.49 g, 98%).
