실험 절차

In a manner similar to the method described in Example 25a, rac-(2R,3S,4R,5S)-5-(4-azido-2,2-dimethyl-butyl)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 120b (0.5 g, 0.86 mmol) was reacted with trifluoroacetic acid in dichloromethane at room temperature to give rac-(2R,3S,4R,5S)-5-(4-azido-2,2-dimethyl-butyl)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a yellow solid (0.54 g, 96%).
