The reaction solution was cooled to room temperature and partitioned into ethyl acetate and water. The organic layer was separated and concentrated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate, then ethyl acetate:methanol=20:1) to obtain the title compound (43 mg, 80%).
