Reaction Steps

To a stirred solution of 6-(1-benzofuran-2-yl)-4-methoxy-2-(trifluoromethyl)quinoline (0.930 g, 2.71 mmol) in HOAc (30 mL) at 0° C. was added KOAc (0.319 g, 3.25 mmol). The reaction was stirred at this temperature for 10 minutes, and then a solution of Br2 (0.154 mL, 2.98 mmol) in HOAc (5 mL) was added dropwise to it over a period of ˜10 minutes. The reaction mixture was allowed to warm to room temperature and stirred for 2.5 hours. The reaction mixture was then diluted with H2O (10 mL). The solid that formed was filtered off and washed with excess H2O and hexane. This solid was then recrystallized from EtOAc:hexane to afford the product (0.750 g, 66%) as a solid. Mass spectrum (+ESI, [M+H]+) m/z 422/424. 1H NMR (500 MHz, DMSO-d6): δ 8.95 (s, 1H), 8.65 (d, 1H, J=8.9 Hz), 8.29 (d, 1H, J=8.9 Hz), 7.80 (d, 1H, J=8.1 Hz), 7.66 (d, 1H, J=8.1 Hz), 7.36-7.58 (m, 3H), and 4.26 ppm (s, 3H).
