Procedure

To a solution of (3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-(cyclopent-2-enyl)-3-(2,3-dihydroxypropyl)-3-methylpiperidin-2-one (Example 102, Step D) (286 mg, 0.603 mmol) in THF (3 mL) and water (3 mL) was added sodium periodate (258 mg, 1.206 mmol) at room temperature. The slurry was stirred at room temperature for 1 h and then diluted with EtOAc and the layers were separated. The organic layer was washed with sat. Na2S2O3 and sat. aq. NaCl solution and dried over Na2SO4 and concentrated under reduced pressure to provide the title compound.
