実験手順
In a manner similar to the method described in Example 25a, rac-(2R,3R,4R,5S)-4-(4-chloro-2,5-difluoro-phenyl)-3-(3-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 109b (1.5 g, 2.8 mmol) was reacted with trifluoroacetic acid in dichloromethane at room temperature to give rac-(2R,3R,4R,5S)-4-(4-chloro-2,5-difluoro-phenyl)-3-(3-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a off white solid (1.5 g, 91%).
