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 (86.2 mg, 0.2 mmol) prepared in Example 1d, (R)-2-amino-4-methyl-pentan-1-ol (35.16 mg, 0.3 mmol), HATU (76 mg, 0.2 mmol) and iPr2NEt (0.1 mL, 0.55 mmol) in CH2Cl2 (2 mL) was stirred at rt overnight. The mixture was then diluted with CH2Cl2 and washed with water, brine. The organic phase was separated, filtered and dried over Na2SO4. The mixture was then concentrated and purified by reverse phase chromatography (30-95% of MeCN/water) to give (2R,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid ((R)-1-hydroxymethyl-3-methyl-butyl)-amide (26.2 mg, 24.7%).
