Reaction Steps

A mixture of methyl 4-chloro-2-(difluoro(4-fluorophenyl)methyl)quinazoline-7-carboxylate (1 g, 2.7 mmol), 5-methyl-1H-pyrazol-3-amine (0.32 g, 3.27 mmol), DIEA (0.62 mL, 3.5 mmol), and KI (0.5 g, 3 mmol) in DMF (20 mL) was stirred at rt for 20 h. The mixture was diluted with H2O and stirred for 1 h, and then the precipitated solid was collected by filtration, washed with H2O, and dried to afford methyl 2-(difluoro(4-fluorophenyl)methyl)-4-(5-methyl-1H-pyrazol-3-ylamino)quinazoline-7-carboxylate (1.17 g, 100%). 1H NMR (300 MHz, DMSO-d6) δ 2.24 (s, 3 H), 3.97 (s, 3 H), 6.31 (s, 1 H), 7.15-7.50 (m, 2 H), 7.62-7.90 (m, 2 H), 7.99-8.13 (m, 1 H), 8.20-8.55 (m, 1 H), 8.69-9.04 (m, 1 H), 10.96 (s, 1 H), 12.28 (s, 1 H); LC-MS (ESI) m/z 428 (M+H)+.
