After the mixture was stirred at room temperature for 1 h, the solvent was distilled off in vacuo. The residue was partitioned between CH2Cl2 (50 mL) and brine (50 mL). Organic phase was dried over Na2SO4 and concentrated in vacuo. Obtained solid was washed with hexane to obtain the title compound (382 mg, 1.70 mmol, 63%) as a white solid. 1H NMR (CDCl3) δ: 1.53 (9H, s), 4.66 (2H, s), 7.93 (1H, s), 8.08 (1H, d, J = 5.9 Hz), 8.28 (1H, d, J = 5.9 Hz), 8.32 (1H, s). ESI-MS m/z: 225 (M+H)+.
