After leaving to cool, a saturated aqueous ammonium chloride solution was added, and the organic layer was extracted with ethyl acetate and dried over sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography [ethyl acetate:dichloromethane:methanol=5:5:1 (v/v)] to give 245 mg of the title compound as a solid.
