The resulting mixture was maintained at ambient temperature for about 12 hours. Following standard extractive workup with ethyl acetate, the crude product was purified by flash column chromatography on silica gel (1×15 cm, dichloromethane/methanol/NH4OH=90/8/1 elution) to give the title product (49 mg, 20%). 1H NMR (300 MHz, CDCl3) δ 7.26-7.23 (m, 1H), 7.06 (s, 1H), 7.00 (d, 1H, J=7.5 Hz), 6.95 (d, 1H, J=6.9 Hz), 5.18 (s, 2H), 4.71 (d, 1H, J=5.7 Hz), 3.48 (s, 3H), 2.84-2.62 (m, 2H), 2.46 (s, 3H); LC-MS: m/z=212 (MH)+.
