Procedure

To a solution of 4-chloro-2-(difluoro(4-fluorophenyl)methyl)quinazoline (0.150 g, 0.487 mmol) in DMF (2 mL) at rt were added potassium iodide (0.081 g, 0.487 mmol), DIEA (0.093 mL, 0.535 mmol) and 5-methyl-1H-pyrazol-3-amine (0.048 g, 0.487 mmol). After stirring the reaction mixture at rt overnight, the reaction was quenched by adding water (15 mL). The precipitate was collected by filtration and washed with H2O. The crude solid was triturated with MeOH. 2-(Difluoro(4-fluorophenyl)methyl)-N-(5-methyl-1H-pyrazol-3-yl)quinazolin-4-amine was obtained as an off-white solid (0.125 g, 69%). 1H NMR (300 MHz, DMSO-d6) δ 2.24 (s, 3H), 6.31 (s, 1H), 7.34 (m, 2H), 7.68 (m, 3H), 7.87 (m, 2H), 8.68 (m, 1H), 10.69 (s, 1H), 12.20 (s, 1H); LC-MS (ESI) m/z 370 (M+H)+.
