Procedure

To a solution of rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(1-hydroxymethyl-cyclohex-3-enylmethyl)-pyrrolidine-2-carboxylic acid [2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethyl]-amide (0.28 g, 0.43 mmol) prepared in Example 117d in ethyl acetate (10 mL) was added PtO2 (0.1 g). The suspension was shaken vigorously under H2 atmosphere (50 psi) for 1 h. The mixture was filtered through a short pad of celite. The filtrate was concentrated to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(1-hydroxymethyl-cyclohexylmethyl)-pyrrolidine-2-carboxylic acid [2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethyl]-amide as a white solid (0.27 g, 96%)
