反応手順

To a solution of 4-(4-phenylquinazolin-2-ylamino)benzoyl chloride (1.56 g, 4.35 mmol) and Hunig's base (1.3 mL, 7.5 mmol) in tetrahydrofuran (50 mL) and dichloromethane (10 mL) was added 2-methyl-5-nitroaniline (726 mg, 4.78 mmol), and the reaction was allowed to stir at rt overnight. The mixture was concentrated on a rotary evaporator and purified by flash column chromatography to give N-(2-methyl-5-nitrophenyl)-4-[(4-phenylquinazolin-2-yl)amino]benzamide (522 mg, 58%) as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 10.46 (s, 1H), 10.03 (s, 1H), 8.49 (d, 1H), 8.27 (d, 2H), 8.10 (d, 3H), 7.80 (m, 5H), 7.73 (m, 3H), 7.66 (d, 1H), 7.50 (dt, 1H), 2.50 (s, 3H). MS (EI) for C28H21N5O3: 476.0 (MH+).
