The reaction liquid was stirred for 3 hours with cooling with ice, and then water was poured into the reaction solution, extracted with ethyl acetate and dried with anhydrous sodium sulfate. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through silica gel column chromatography (developing solvent: hexane/ethyl acetate=3/1) to obtain the entitled compound.
