The mixture was poured into water and extracted with EtOAc. The organic layer was separated, washed with saturated NaHCO3 solution and brine successively, dried over MgSO4 and concentrated in vacuo. The residue was purified by column chromatography (EtOAc/MeOH), followed by crystallized from hot EtOAc to give the title compound (15.3 mg) as pale yellow crystals.
