Intermediate 1 (0.7 g) was dissolved in methanol (20 ml) and the solution cooled to 0° C. A solution of oxone (1.93 g) in water (20 ml) was added and the mixture was stirred under nitrogen for 2 h at room temperature. The mixture was extracted with dichloromethane, the layers were separated (hydrophobic frit), and the organic layer evaporated to give the title compound as a yellow oil which crystallised on standing (0.79 g).
