실험 절차

1.77 g of 1 (10 mmol) in 50 ml of glacial acetic acid containing 6.5 g of MCPBA (57-85%) was refluxed for 3 hours. Acetic anhydride (40 ml) was added to the hot reaction mixture and the refluxing was continued for another half an hour. The clear brown solution was evaporated to dryness and the solid was stirred with ether (100 ml) and filtered. The solid was crystallized from ethanol to give 1.55 g (66%) of 2.
