The solvent was evaporated under reduced pressure, and the residue was dissolved in ethyl acetate and washed with saturated aqueous sodium hydrogen carbonate solution. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column (ethyl acetate/hexane=1/1 to ethyl acetate), and the obtained product was recrystallized from ethanol-water to give the title compound as colorless needle crystals (0.16 g, 44%).
