실험 절차

Ozone was bubbled through a solution of ((3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-1-((S)-1-(N-methylcyclopropanesulfonamido)butan-2-yl)-2-oxopiperidin-3-yl)methyl methanesulfonate (Example 414, Step E, 1.12 g, 1.703 mmol) in 10% MeOH-DCM at −78° C. until a blue color developed. The reaction was purged with nitrogen gas followed by addition of dimethyl sulfide (1.251 ml, 17.03 mmol). The reaction was warmed to room temperature. The crude material was purified by chromatography on 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.
