실험 절차

Triflic anhydride (0.08 ml) was added to a solution of the product from step (h) (147 mg) and pyridine (0.08 ml) in dichloromethane (2 ml) and stirred for 18 hours. Water was added and the mixture was extracted with dichloromethane. The organic layer was dried (MgSO4), evaporated and purified (SiO2, petrol:ether 3:2 as eluent) to give the sub-title compound as a white foam (166 mg).
