実験手順

In a manner similar to the method described in Example 25a, rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-cyclohexylmethyl-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 59b (1.9 g, 3.6 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-phenyl)-4-cyano-5-cyclohexylmethyl-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a white solid (2.1 g, 99%).
