After 3 hours, water (20mL) was added to the mixture and extracted with diethyl ether (2×100mL). . The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo (20 °C) to give a brown solid, which was purified by filtration over silica (ethyl acetate/heptane 8/2), yield: 95% (11.4 g). ), pale yellow needles. 1H NMR (CDCl3): 8 8.07 (d, J = 5.3Hz, 1H), 7.76 (d, J = 1.1Hz, 1H), 7.59 (dd, J = 5.0/0.11. Hz, 1H ).13C NMR (CDCl3): δ 151.7, 149.6, 133.0, 131.5, 106.6. MS (EI) m/z 240 (M+1). More
