Reaction Steps

A mixture of (4-chloroquinazoline-2-yl)(4-fluorophenyl)methanone from Example 3 (580 mg, 2.02 mmol), and 3-amino-1H-pyrazole-5-carbonitrile (218 mg, 2.02 mmol) in DMF (5 mL) was stirred at rt overnight. MeOH (10 mL) was then added to this mixture, and the precipitate was filtered washed with MeOH, and dried to afford 3-(2-(4-fluorobenzoyl)quinazolin-4-ylamino)-1H-pyrazole-5-carbonitrile (170 mg, 23.4%) 1H NMR (300 MHz, DMSO-d6) δ 6.89 (s, 1H), 7.40 (d, 2H), 7.83 (s, 1H), 7.98 (m, 2H), 8.11 (m, 2H), 8.56 (s, 1H), 11.18 (s, 1H), 13.84 (s, 1H); LC-MS (ESI) m/z 359 (M+H)+.
