The reaction mixture was diluted with ethyl acetate (25 ml), washed with 5% aqueous sodium sulfite solution, 2% aqueous sodium carbonate solution and saturated brine, dried over anhydrous sodium sulfate and concentrated. Diethyl ether was added to the residue, and the precipitate was collected by filtration, washed with diethyl ether and dried to give the title compound as a white powder (111 mg, 0.24 mmol, quant.).
