Reaction Steps

A mixture of 4-methylthio-6H-imidazo[4,5-g]quinazoline (0.5 g, 1.6 mmol) [Leonard, N. J.; Morrice, A. G.; Sprecker, M. A.; J. Org. Chem., 1975, 40, 356-363], 3-bromoaniline (0.35 g, 2.0 mmol), and 3-bromoaniline hydrochloride (0.4 g, 1.9 mmol) in isopropanol (200 mL) is heated under reflux for 1 h to give a precipitate of 4-(3-bromoanilino)-6H-imidazo[4,5-g]quinazoline hydrochloride (0.63 g, 72%). 1H NMR (DMSO) δ9.93 (1H, brs), 9.01 (1H, s), 8.66 (2H, s), 8.39 (1H, s), 8.04 (2H, m), 7.39 (1H, t, J=7.9 Hz), 7.31 (1H, brd, J=8.0 Hz). ##STR22##
