The solvent was evaporated under reduced pressure and the reaction mixture was diluted with ethyl acetate and washed with saturated ammonium chloride solution and brine. After evaporation of the solvent, the residue was purified by flash chromatography using SP1® Purification System (30% to 70%, dichloromethane-ethyl acetate) to obtain 67 mg (37% yield) of the title compound.
