A mixture of N-(5-cyano-2-methylphenyl)-4-[(4-phenylquinazolin-2-yl)amino]benzamide (273 mg, 0.600 mmol), prepared as described in Example 10, trimethylsilylazide (160 μL, 1.2 mmol), and dibutyltin oxide (36 mg, 0.060 mmol) in dimethoxyethane (6 mL) was reacted in the microwave reactor (120° C., 100 psi, 2). The reaction was then concentrated on a rotary evaporator and the residue was purified by preparative reverse phase HPLC to give N-[2-methyl-5-(1H-tetrazol-5-yl)phenyl]-4-[(4-phenylquinazolin-2-yl)amino]benzamide (242 mg, 81%) as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 10.36 (s, 1H), 9.91 (s, 1H), 8.20 (d, 2H), 8.13 (d, 1H), 8.03 (d, 2H), 7.91-7.79 (m, 5H), 7.67-7.63 (m, 3H), 7.53 (d, 1H), 7.42 (ddd, 1H), 2.36 (s, 3H). MS (EI) for C29H22N8O: 499.3 (MH+).
