Procedure
A solution of the sulphide of step (a) above (1.15 mmoles) in methanol (70 ml)/dichloromethane (50 ml) was stirred at 10°. Solid m-chloroperbenzoic acid (80%; 1.38 mmoles) was added portionwise over 5 minutes. The solution was stirred at 10° for a further 30 minutes and then concentrated to approximately 25 ml. Silica gel (approximately 10 g) was added and the remaining solvent removed. Flash chromatography using dichloromethane containing 20 % ethyl acetate as eluant gave a pale orange solid (0.20 g) which was slurried in dichloromethane (50 ml) and filtered to give the title compound as an off-white solid, mp 208°-9° (dec).
