Procedure

A mixture of 4-methylthioimidazo[4,5-h]quinazoline (0.216 g, 1 mmol), 3-bromoaniline (0.25 g, 1.5 mmol), and 3-bromoaniline hydrochloride (0.31 g, 1.5 mmol) in N-methylpyrrolidone (50 mL) is heated 120° C. for 2 h. The solvent is removed under vacuum and the residue is triturated with EtOH to give a solid which is recrystallized from MeOH to give 4-(3-bromoanilino)imidazo[4,5-h]quinazoline hydrochloride (0.23 g, 61%). 1H NMR (DMSO) δ11.11 (1H, brs), 8.93 (2H, s), 8.66 (1H, d, J=9.0 Hz), 8.11 (1H, brs), 8.07 (1H, d, J=9.0 Hz), 7.83 (1N, brd, J=6.8 Hz), 7.50-7.40 (2H,m).
