Procedure

In a manner similar to the method described in Examples 42c and 42d, rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(1-methyl-cyclohexylmethyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid prepared in Example 102c (0.72 g, 1.15 mmol) was reacted with 2-((S)-2,2,5,5-tetramethyl-[1,3]dioxolan-4-yl)-ethylamine prepared in Example 131a (0.4 g, 2.3 mmol), HATU (0.79 g, 2.1 mmol) and iPr2NEt (1 mL, 5.8 mmol) in CH2Cl2 at room temperature for 20 h, then reacted with aqueous HCl solution in tetrahydrofuran at room temperature to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(1-methyl-cyclohexylmethyl)-pyrrolidine-2-carboxylic acid ((S)-3,4-dihydroxy-4-methyl-pentyl)-amide as a white solid (0.25 g, 42%).
