Reaction Steps

A mixture of methyl 4-methyl-3-[({4-[(4-phenylquinazolin-2-yl)amino]phenyl}carbonyl)amino]benzenecarboximidoate (50 mg, 0.10 mmol), formylhydrazine (30 mg, 0.5 mmol) and Hunig's base (17 μL, 0.20 mmol) in ethanol (2 mL) was heated to 150° C. in a sealed tube overnight. The reaction was cooled to rt and concentrated on a rotary evaporator. The residue was purified by preparative reverse phase HPLC to give N-[2-methyl-5-(1H-1,2,4-triazol-5-yl)phenyl]-4-[(4-phenylquinazolin-2-yl)amino]benzamide (10.9 mg, 22%) as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 10.34 (s, 1H), 9.84-9.82 (m, 2H), 8.62 (s, 1H), 8.19 (d, 2H), 8.06-7.99 (m, 3H), 7.90-7.78 (m, 5H), 7.66-7.63 (m, 3H), 7.42 (ddd, 1H), 7.36 (d, 1H), 2.36 (s, 3H). MS (EI) for C30H23N7O: 498.2 (MH+).
