Reaction Conditions

Reaction Steps

To a solution in acetone (107 mL) of the compound (2.46 g) obtained in step (3) above, p-toluenesulfonic acid monohydrate (2.04 g) was added and the mixture was stirred at 50° C. for two hours. After cooling the reaction mixture to room temperature, a saturated aqueous solution of sodium hydrogencarbonate was added to it under cooling with ice and two extractions were conducted with ethyl acetate. The combined organic layers were dried over anhydrous magnesium sulfate; thereafter, the desiccant was removed by filtration and the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=100:0-80:20) to give the titled compound as a colorless solid (0.67 g).
