The mixture was stirred at RT for 1.5 h. The reaction mixture was diluted with ethyl acetate and water. The organic layer was washed with water and brine, dried over sodium sulfate, and the solvent was evaporated. The residue was purified by column chromatography (hexane/EtOAc) to give the title compound (0.056 g, 48%) as an off-white solid. 1H NMR (400 MHz, CDCl3): δ ppm 9.74 (s, 1H), 7.78 (s, 1H), 7.44 (d, 1H), 7.27-7.37 (m, 2H), 7.21 (dd, 1H), 7.08-7.13 (m, 1H), 6.98 (d, 1H), 6.74-6.86 (m, 3H), 6.63 (s, 1H), 4.66 (d, 2H), 1.50 (s, 9H).
