This reaction solution was 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 (heptane:ethyl acetate=2:1, 1:1, ethyl acetate) to obtain the title compound (4.6 mg, 5.3%).
