Procedure

A solution of ((3R,5R,6S)-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((S)-1-(N-methylcyclopropanesulfonamido)butan-2-yl)-2-oxo-3-(2-oxoethyl)piperidin-3-yl)methyl methanesulfonate (Example 414, Step F, 1.0 g, 1.516 mmol) in MeOH was treated with Oxone (0.932 g, 1.516 mmol) over a weekend. The reaction mixture was diluted with DCM and water. The organic extract was washed with satd NaCl and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as a white solid. The product was purified by chromatography through a RediSep® pre-packed silica gel column (Teledyne Isco, Lincoln, Nebr.) (12 g), eluting with a gradient of 0% to 80% EtOAc in hexane, to provide the title compound as an oil.
