Procedure

In a manner similar to the method described in Examples 118a, rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-[2-(3,6-dihydro-2H-pyran-4-yl)-2-methyl-propyl]-pyrrolidine-2-carboxylic acid ((S)-3,4-dihydroxy-butyl)-amide prepared in Example 127e (0.28 g, 0.45 mmol) was treated with PtO2 and H2 in ethyl acetate to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-[2-methyl-2-(tetrahydro-pyran-4-yl)-propyl]-pyrrolidine-2-carboxylic acid ((S)-3,4-dihydroxy-butyl)-amide as a off white solid (0.15 g, 54%)
