実験手順
To refluxing (˜300° C.) dowtherm A (100 ml) (mixture of biphenyl and diphenyl ether) was added ethyl (2Z)-3-[(4-bromo-3-methoxyphenyl)amino]-3-phenylacrylate (6.5 g, 17.27 mmol) in DOWTHERM A (5 mL, washed with 1 mL). Almost immediately, white solid begins to precipitate out of solution. Refluxing was continued for 40 min, and the reaction was cooled to RT and let stand for 1 h. The white solid was then filtered off, and the washed extensively with hexanes to give 6-bromo-7-methoxy-2-phenylquinolin-4(1H)-one as white crystals (4.72 g, 83%). 1H NMR (400 MHz, DMSO-d6): 11.69 (s, 1H), 8.19 (s, 1H), 7.82 (m, 2H), 7.59 (m, 3H), 7.35 (s, 1H), 6.33 (s, 1H), 3.96 (s, 3H). LRMS (CI, [M+H]) Calc'd=330.0. found=330.1.
