Procedure
A solution of N-((S)-2-((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-ethyl-2-oxopiperidin-1-yl)-2-cyclopropylethyl)cyclopropanesulfonamide (Example 254, Step A, 80 mg, 0.139 mmol) in THF (375 μL), water (250 μL) and t-butanol (208 μL) was treated with 4-methylmorpholine N-oxide (57.0 mg, 0.486 mmol) followed by 2.5% osmium tetroxide in t-butanol (45.6 μL, 3.47 μmol). After stirring at ambient temperature for 16 h, the mixture was diluted with ethyl acetate and washed with water and sat. aq. NaCl solution. The organic layer was dried over sodium sulfate and concentrated to provide the title compound as a mixture of diastereomers (85 mg) which was used directly in the next step. Mass Spectrum (ESI) m/z=609.1 (M+1)
