Reaction Steps

In a manner similar to the method described in Example 1e, rac-(2R,3R,4R,5R)-5-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-3-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid prepared in Example 32d (0.6 g, 1.1 mmol) was reacted with 3-amino-1-propanol (Aldrich) (0.6 g, 8 mmol), HATU and iPr2NEt in CH2Cl2 at room temperature to give rac-(2R,3R,4R,5R)-5-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-3-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (3-hydroxy-propyl)-amide as a yellow solid (0.12 g, 22%).
