After replacement with nitrogen, the mixture was stirred at 100° C. for 1.5 hours. The reaction mixture was then poured into a saturated aqueous sodium bicarbonate solution, followed by extraction with dichloromethane. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (hexane:ethyl acetate=2:1) to give the target compound as a colorless oil (54.7 mg, 87%). followed by extraction with dichloromethane The organic layer was dried over anhydrous magnesium sulfate filtered concentrated under reduced pressure The resulting residue was purified by silica gel chromatography (hexane:ethyl acetate=2:1)
