A mixture of (4-chloroquinazolin-2-yl)(4-fluoro-3-methoxyphenyl)methanone (337 mg, 1.06 mmol), 5-methyl-1H-pyrazol-3-amine (206 mg, 2.12 mmol), potassium iodide (528 mg, 3.18 mmol) and DIEA (0.37 mL, 2.13 mmol) in DMF (10 mL) was stirred at rt for 20 h. To the mixture was added water (80 mL) and the resulting solid was collected by filtration and washed with water and then diethyl ether. The solid was dried to afford (4-fluoro-3-methoxyphenyl)(4-(5-methyl-1H-pyrazol-3-ylamino)quinazolin-2-yl)methanone as a yellow solid (300 mg, 75%). 1H NMR (300 MHz, DMSO-d6) δ ppm 2.19 (s, 3H), 3.90 (s, 3H), 6.55 (s, 1H), 7.38 (dd, J=11.1, 8.4 Hz, 1H), 7.59 (m, 1H), 7.68 (dd, J=7.8, 7.8 Hz, 1H), 7.77-7.94 (m, 3H), 8.75 (d, J=7.8 Hz, 1H), 10.69 (br s, 1H), 12.23 (br s, 1H); LC-MS (ESI) m/z 378 (M+H)+.
