Procedure

In a manner similar to the method described in Example 1e, rac-(2R,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid prepared in Example 25a (1 g, 1.8 mmol) was reacted with N-Boc-1,3-diaminopropane (Aldrich) (0.7 g, 4 mmol), HATU (1.4 g, 3.7 mmol) and iPr2NEt (2.8 g, 21 mmol) in CH2Cl2 (100 mL) at room temperature for 60 h to give rac-(3-{[(2R,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-propyl)-carbamic acid tert-butyl ester as a white solid (0.92 g, 87%).
