실험 절차

To a solution of methyl 4-bromo-2-(difluoro(5-fluoropyridin-2-yl)methyl)quinazoline-8-carboxylate (27 g, 65.5 mmol) in dioxane (300 mL) was added 5-methyl-1H-pyrazol-3-amine (12.7 g, 131 mmol) and the mixture was stirred at 50° C. overnight. The mixture was concentrated and the residue was triturated with water (1 L). The solid was collected by filtration, washed with water, and dried in air to afford methyl 2-(difluoro(5-fluoropyridin-2-yl)methyl)-4-((5-methyl-1H-pyrazol-3-yl)amino)quinazoline-8-carboxylate as a solid. (26.7 g, 95%). LC-MS (ESI) m/z 429.6 (M+H+). 1H NMR (500 MHz, DMSO-d6) δ 12.23 (1H, s), 10.86 (1H, s), 8.82 (1H, d, J=8.2 Hz), 8.67 (1H, d, J=2.6 Hz), 7.99 (3H, m), 7.68 (1H, t, J=8.0 Hz), 6.05 (1H, s), 3.83 (3H, s), 2.19 (3H, s).
