Procedure
In a manner similar to the method described in Example 1e, rac-(2R,3R,4R,5S)-3,5-bis-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid trifluoroacetic acid prepared in Example 42b (0.3 g, 0.5 mmol) was reacted with 2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethylamine (0.3 g, 2 mmol), HATU (0.3 g, 0.75 mmol) and iPr2NEt (0.6 g, 4 mmol) in CH2Cl2 (30 mL) at room temperature for 20 h to give rac-(2R,3R,4R,5S)-3,5-bis-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-pyrrolidine-2-carboxylic acid [2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethyl]-amide as a off white solid (0.25 g, 83%).
