The reaction liquid was diluted with chloroform, washed with aqueous saturated ammonium chloride, aqueous saturated sodium bicarbonate and saturated saline in order, and dried with anhydrous sodium sulfate. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through partitioning thin-layer chromatography (Kieselgel™ 60F254, Art 5744 (by Merck), chloroform/methanol=10/1) to obtain the entitled compound as a white solid.
