Procedure

Sodium periodate (21.03 g, 98 mmol) was added slowly to a solution containing ruthenium(III) chloride hydrate (0.277 g, 1.229 mmol) and (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methylpiperidin-2-one (4.6 g, 12.29 mmol; Example 71, step D) in acetonitrile (35.1 mL), ethyl acetate (35.1 mL) and water (52.7 mL) while maintaining a temperature below 20° C. The resulting mixture was then stirred for 2 h at room temperature. Next, the reaction was filtered and concentrated, and the resulting residue was further processed by dissolving in ethyl acetate. The organics were washed with water and brine, dried over MgSO4, filtered and concentrated. Next, the residue was dissolved in a small amount of a mixture of ether and methanol (1:1) and a 2M solution of (trimethylsilyl)diazomethane in diethyl ether (12.29 ml, 24.58 mmol) was added. This solution was then allowed to stir at ambient temperature overnight. The solution was concentrated and the resulting residue was purified on silica gel (eluent: hexane/ethyl acetate 0 to 100%, gradient elution) to give the title compound. Mass Spectrum (ESI) m/z=406 (M+1).
