Aqueous sodium hydrogen carbonate solution was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with water, dried and the solvent was evaporated. The residue was purified by silica gel column chromatography (hexane-ethyl acetate=4:1) to give the title compound (3.3 g, yield 38%).
