Procedure

To a solution of (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methyl-1-(pyrimidin-4-yl)piperidin-2-one (Example 110, Step B) (60 mg, 0.13 mmol) in a mixture of tetrahydrofuran (2.7 mL) and water (880 μL) was added osmium tetroxide (1.7 mg, 6.6 μmol). After 5 minutes, sodium periodate (89 mg, 0.46 mmol) was added and the reaction mixture was stirred for 14 hours. The reaction mixture was filtered through Celite® (J. T. Baker, Phillipsberg, N.J., diatomaceous earth) and washed with EtOAc and water. The organic layer was washed with sat. aq. NaCl solution, dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure. Purification of the residue by flash chromatography (0 to 75% EtOAc/hexanes, gradient elution) provided the title compound as a colorless solid.
