Procedure
7.1 g of crude (13) product was dissolved in 150 ml of ethanol. 1 ml of concentrated sulfuric acid was added and the solution was stirred at reflux for 2 hours. 50 ml of saturated aqueous sodium bicarbonate was added to the cooled mixture and the mixture was extracted twice with 100 ml of dichloromethane. The combined organic extracts were dried over anhydrous sodium sulfate and evaporated. The crude product was distilled at 100° C. at a reduced pressure affording a slightly yellow liquid (3.2 g).
