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 3-amino-2,2-dimethyl-1-propanol (TCI-US) (0.2 g, 2 mmol), HATU (0.2 g, 0.5 mmol) and iPr2NEt (0.2 g, 1.6 mmol) in CH2Cl2 (20 mL) at room temperature for 20 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 (3-hydroxy-2,2-dimethyl-propyl)-amide as a white solid (0.16 g, 83%).
