To a solution of 2-(1H-indazol-5-yl)-3-[methyl(propan-2-yl)amino]quinoxaline-6-carbonitrile (150 mg, 0.44 mmol) in DMSO (15 ml) was added dibromozinc (50 mg, 0.22 mmol), azidosodium (86 mg, 1.32 mmol), and water (2 ml), and the resulting mixture was stirred overnight at 130° C. in an oil bath. The solution was diluted with water (200 ml) and adjusted to pH 4 with HCl (2N), extracted with ethyl acetate (5×50 ml), dried over anhydrous magnesium, and concentrated in vacuo to give a residue, which was purified by a silica gel column (10% methanol in dichloromethane) to afford 3-(1H-indazol-5-yl)-N-methyl-N-(propan-2-yl)-7-(1H-tetrazol-5-yl)quinoxalin-2-amine as a yellow solid (38.5 mg, 23%).
