実験手順

To a solution of the compound obtained in Example 14 (2) (33.7 mg) in a mixture of tetrahydrofuran/water (3:1, 4 ml), OXONE (registered trademark) (134 mg) was added at 15 to 30° C. and the mixture was stirred for 15 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 28.8 mg of the desired product as a white powder.
