実験手順

The product from Step 1 (1 g) and m-chloroperbenzoic acid (1.19 g) were stirred at ambient temperature in dichloromethane (10 ml) for 18 hours. Sodium metabisulphite (1.19 g) in water (5 ml) was added and stirring was continued for 0.5 hours after which the reaction mixture was extracted with dichloromethane. The combined organics were washed with saturated sodium bicarbonate solution, dried (MgSO4) and evaporated to give the sub-title compound (0.34 g).
