실험 절차

To 4,8-dichloro-2-(difluoro(5-fluoropyridin-2-yl)methyl)quinazoline (263 mg, 0.77 mmol) in DMA (2.0 mL) were added tert-butyl 3-amino-5-methyl-1H-pyrazole-1-carboxylate (300 mg, 1.53 mmol) and HOAc (0.102 mL), and the mixture was heated at 100° C. for 5 h. The mixture was allowed to cool to rt and was purified by preparative reverse-phase HPLC (diphenyl column eluting over 40 mins with a gradient of 25 to 80% acetonitrile (containing 0.05% HOAc) and water (containing 0.05% HOAc) to afford 8-chloro-2-(difluoro(5-fluoropyridin-2-yl)methyl)-N-(5-methyl-1H-pyrazol-3-yl)quinazolin-4-amine as a colorless solid (51 mg, 16%). 1H NMR (300 MHz, DMSO-d6) δ 12.23 (br s, 1H), 10.87 (br s, 1H), 8.65-8.67 (m, 2H), 8.01-8.08 (m, 3H), 7.61 (dd, J=9, 6 Hz, 1H), 5.94 (s, 1H), 2.17 (s, 3H). LCMS (ESI) m/z 405 (M+H)+.
