After completion of the reaction, 1N hydrochloric acid was added to make it acidic, followed by extraction with ethyl acetate, the organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=1/1) to obtain 97 mg of the desired product.
