Procedure

To a stirred solution of N-[2-methyl-5-(1H-tetrazol-5-yl)phenyl]-4-[(4-phenylquinazolin-2-yl)amino]benzamide (100 mg, 0.20 mmol) in dimethylformamide (2 mL) was added potassium carbonate (83 mg, 0.60 mmol) and methyl iodide (100 μL, 1.6 mmol) and the mixture was allowed to stir at rt overnight. The mixture was purified by preparative reverse phase HPLC to give N-[2-methyl-5-(2-methyl-2H-tetrazol-5-yl)phenyl]-4-[(4-phenylquinazolin-2-yl)amino]benzamide (51 mg, 50%). 1H NMR (400 MHz, DMSO-d6): δ10.34 (s, 1H), 9.84 (s, 1H), 8.20 (d, 2H), 8.16 (d, 1H), 8.02 (d, 2H), 7.91-7.78 (m, 5H), 7.66-7.64 (m, 3H), 7.47 (d, 1H), 7.42 (ddd, 1H), 4.43 (s, 3H), 2.35 (s, 3H). MS (EI) for C30H24N8O: 513.3 (MH+).
