Procedure

To (4-chloro-7-(trifluoromethyl)quinazolin-2-yl)(4-fluorophenyl)methanone (1 g, 2.82 mmol) in DMF (10 mL) were added DIEA (0.49 mL, 2.82 mmol), 5-methyl-1H-pyrazol-3-amine (823 mg, 8.47 mmol), and potassium iodide (468 mg, 2.82 mmol) and the mixture was stirred at rt for 2 h. To the reaction mixture was added water followed by extraction with EtOAc. The organic phases were dried over sodium sulfate. The solvent was concentrated and the residue was dried under high vacuum overnight. The crude solid (240 mg) was purified on reverse-phase preparative HPLC (elution gradient of 40-90% acetonitrile in water with 0.05% acetic acid) to afford (4-fluorophenyl)(4-(5-methyl-1H-pyrazol-3-ylamino)-7-(trifluoromethyl)quinazolin-2-yl)methanone as a yellow solid (40 mg, 16%). 1H NMR (300 MHz, DMSO-d6) δ ppm 2.2 (s, 3 H) 6.55 (s, 1 H) 7.35-7.5(m, 3H) 7.9-8.0(m, 1H) 8.05-8.3 (m, 4H) 11.1 (s, 1 H) 12.25 (s, 1 H) LC-MS (ESI) m/z 416 (M+H)+.
