After the extraction with ethyl acetate, the extract was washed with 1 N aqueous sodium hydroxide solution and saturated aqueous common salt solution, and then dried over powdery magnesium sulfate. The solvent was evaporated, and the residue was purified by the silica gel chromatography to obtain the title compound.
