Reaction Steps

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 (0.20 g, 0.36 mmol) was reacted with 4-(2-aminoethyl)-cis-2,6-dimethylmorpholine (Oakwood) (0.20 g, 1.2 mmol), HATU (0.3 g, 0.78 mmol) and iPr2NEt (0.60 g, 4.6 mmol) in CH2Cl2 (20 mL) at room temperature for 20 hrs 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-(cis-2,6-dimethyl-morpholin-4-yl)-ethyl]-amide as a white solid (0.20 g, 94%).
