実験手順
In a manner similar to the method described in Example 25a, rac-(2R,3S,4R,5S)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-3-(2,3-difluoro-phenyl)-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 62b (1.8 g, 3.6 mmol) was reacted with trifluoroacetic acid in dichloromethane at room temperature to give rac-(2R,3S,4R,5S)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-3-(2,3-difluoro-phenyl)-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a white solid (2 g, 100%).
