The reaction mixture was washed with saturated aqueous sodium hydrogen carbonate solution, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the precipitated solid was washed with ethyl acetate to give the title compound as a white powder (0.36 g, 78%).
