Reaction Steps

To a mixture of 5-methyl-1H-pyrazol-3-amine (0.26 g, 2.68 mmol), potassium iodide (0.26 g, 1.57 mmol), and TEA (0.45 mL, 3.23 mmol) in DMF (30 mL) was added (3-chloro-4-fluorophenyl)(4-chloroquinazolin-2-yl)methanone (0.495 g, 1.54 mmol) and the mixture was stirred at rt overnight. Water was added and the precipitated solid was collected by filtration to afford crude (3-chloro-4-fluorophenyl)(4-(5-methyl-1H-pyrazol-3-ylamino)quinazolin-2-yl)methanone (458 mg) which was used directly in the next step. LC-MS (ESI) m/z 382 (M+H)+.
