実験手順
In a manner similar to the method described in Example 25a, rac-(2R,3R,4R,5S)-3-(4-bromo-thiophen-2-yl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 70b (0.9 g, 1.6 mmol) was reacted with trifluoroacetic acid in dichloromethane at room temperature to give rac-(2R,3R,4R,5S)-3-(4-bromo-thiophen-2-yl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a light blue solid (0.9 g, 92%).
