After the extraction with dichloromethane, the extract was washed with saturated aqueous sodium hydrogencarbonate solution and then with saturated aqueous NaCl solution, and dried over anhydrous magnesium sulfate. The solvent was evaporated. The residue was purified by the silica gel chromatography with ethyl acetate as the eluent to obtain the title compound.
