Procedure

In a manner similar to the method described in Example 25a, rac-(2R,3S,4R,5S)-5-[2-(1-benzyl-1,2,3,6-tetrahydro-pyridin-4-yl)-2-methyl-propyl]-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid tert-butyl ester prepared in Example 127b (1.5 g, 2.2 mmol) was reacted with trifluoroacetic acid in dichloromethane at room temperature to give rac-(2R,3S,4R,5S)-5-[2-(1-benzyl-1,2,3,6-tetrahydro-pyridin-4-yl)-2-methyl-propyl]-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid trifluoroacetic acid as a yellow solid (1.6 g, 98%).
