Participants

Reaction Steps

To a stirred solution of the sulfoxide from Example 5 (34 mg, 0.08 mmol) in methanol (1 ml) was added a solution of oxone (49 mg, 0.08 mmol) in water (1 ml). After 2 hours the reaction mixture was concentrated under reduced pressure and the residue was partitioned between dichloromethane (5 ml) and water (5 ml). The organic layer was dried over magnesium sulfate, filtered and concentrated under reduced pressure. The crude product mixture was purified by flash chromatography on silica gel eluting with dichloromethane:methanol (100:0, 99:1 then 98:2, by volume) to give the title compound as a colourless oil (12 mg).
