The reaction mixture was poured into ice water (70 mL), and the mixture was extracted with ethyl acetate (80 mL×3). The organic layers were combined, washed successively with water (50 mL) and saturated brine (30 mL), dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=95/5→20/80). The obtained residue was recrystallized from ethyl acetate to give the title compound (2.47 g, 63%) as white crystals.
