The reaction mixture was cooled to room temperature, diluted with ethyl acetate, washed successively with saturated aqueous sodium bicarbonate and saturated brine, and dried over anhydrous sodium sulfate. After removal of the sodium sulfate by filtration, the organic solvent was evaporated off in vacuo. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=19:1) to give the title compound (161 mg) as a colorless liquid.
