Procedure

A solution of (5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-(dicyclopropylmethyl)-5,6-dihydropyridin-2(1H)-one (Example 115, Step H, 0.826 g, 2.003 mmol) and (1,5-cyclooctadiene)(pyridine) (tricyclohexylphosphine)iridium (i) hexafluorophosphate (0.129 g, 0.160 mmol) in DCM (60.0 ml) was saturated with hydrogen. The resulting mixture was stirred at rt under a hydrogen atmosphere for 2 h, then another 66.0 mg of (1,5-cyclooctadiene)(pyridine) (tricyclohexylphosphine)iridium (i) hexafluorophosphate were added. Stirring under hydrogen atmosphere was continued until LCMS indicated complete saturation of the double bond. The solvent was removed and the crude mixture was purified by chromatography on silica gel (eluting with ethyl acetate:hexane, 10:90) to give the title compound.
