反応手順
To a solution of the compound obtained in Example 13 (1) (210 mg) in a mixture of tetrahydrofuran/methanol (2:1, 15 ml), a 1N aqueous potassium hydroxide solution (1.6 ml) was added and the mixture was stirred at 100° C. for 2 hours. The reaction solution was then poured into water, extracted with dichloromethane, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel preparative thin-layer chromatography (hexane:ethyl acetate=1:1) to obtain 113 mg of the desired product as a white powder.
