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-2-fluoro-phenyl)-4-cyano-5-[2-methyl-2-(5-methyl-furan-2-yl)-propyl]-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 125b (1.3 g, 2.2 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-2-fluoro-phenyl)-4-cyano-5-[2-methyl-2-(5-methyl-furan-2-yl)-propyl]-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a brown solid (1.3 g, 92%).
