Reaction Steps

To a solution of 4-(4-phenylquinazolin-2-ylamino)benzoyl chloride (1.0 g, 2.8 mmol) and Hunig's base (600 μL, 3.4 mmol) in tetrahydrofuran (25 mL) was added 5-bromo-2-methylaniline (600 mg, 3.2 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-(5-bromo-2-methylphenyl)-4-[(4-phenylquinazolin-2-yl)amino]benzamide (1.0 g, 70%) as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 10.34 (s, 1H), 9.77 (s, 1H), 8.18 (d, 2), 7.98 (d, 2H), 7.82 (m, 6H), 7.65 (m, 4H), 7.41 (dt, 1H), 7.35 (dd, 1H), 7.25 (d, 1H), 2.24 (s, 3H). MS (EI) for C28H21BrN4O: 511.2 (MH+).
