Reaction Steps

A solution of 5-methyl-1H-pyrazol-3-amine (13 mg, 0.13 mmol), potassium iodide (15 mg, 0.088 mmol), and DIEA (0.016 mL, 0.088 mmol) in DMF (2 mL) was added to (4-chloro-7-fluoroquinazolin-2-yl)(4-fluorophenyl)methanone (0.027 mg, 0.088 mmol). The resulting solution was stirred at rt overnight and then purified by preparative HPLC (Varian diphenyl reverse phase column, eluted with gradient of solvent B=0.05% HOAC/CH3CN and solvent A=0.05% HOAc/H2O) to give (7-fluoro-4-(5-methyl-1H-pyrazol-3-ylamino)quinazolin-2-yl)(4-fluorophenyl)methanone (10 mg, 31%). 1H NMR (300 MHz, DMSO-d6) δ 2.18 (s, 3H), 6.48 (s, 1H), 7.36 (t, 2H), 7.60 (m, 2H), 8.09 (m, 2H), 8.29 (t, 1H), 10.78 (s, 1H), 12.23 (s, 1H); LC-MS (ESI) m/z 366 (M+H)+.
