The reaction mixture was poured into semi-saturated aqueous sodium hydrogencarbonate, extraction was performed with ethyl acetate and the extract was washed with water and saturated aqueous NaCl. After drying with anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure and the residue was purified by silica gel column chromatography (solvent: n-hexane-ethyl acetate) to yield the title compound (8.9 g, 26%, two steps) as a colorless oil.
