Procedure

In a manner similar to the method described in Example 1e, rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid prepared in Example 26c (0.2 g, 0.36 mmol) was reacted with 2-amino-2-methyl-1-propanol (Fluka) (0.2 g, 2.2 mmol), HATU (0.3 g, 0.78 mmol) and iPr2NEt (0.5 g, 3.8 mmol) in CH2Cl2 (10 mL) at room temperature for 24 h to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (2-hydroxy-1,1-dimethyl-ethyl)-amide as a white solid (0.17 g, 91%).
