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-(2-ethyl-2-hydroxymethyl-butyl)-pyrrolidine-2-carboxylic acid trifluoroacetic acid prepared in Example 111c (1.1 g, 1.8 mmol) was reacted with 2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethylamine (0.78 g, 5 mmol), HATU (1.2 g, 3 mmol) and iPr2NEt (1.6 mL, 9 mmol) in CH2Cl2 at room temperature for 20 h, then reacted with aqueous HCl solution in tetrahydrofuran at room temperature for 2 h to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2-ethyl-2-hydroxymethyl-butyl)-pyrrolidine-2-carboxylic acid ((S)-3,4-dihydroxy-butyl)-amide as a white solid (0.11 g, 10%).
