After water was poured into the reaction mixture and the mixture was extracted with ethyl acetate, the organic layer was successively washed with water and a saturated aqueous NaCl solution and dried with anhydrous sodium sulfate. After the residue obtained by removing the solvent under reduced pressure was purified by silica gel column chromatography (eluting solvent: n-hexane/ethyl acetate=3/1-0/1), it was crystallized from a mixture solvent of methylene chloride-ethyl acetate to give the title compound as a colorless powder (323 mg, yield: 47%).
