(6-Fluoro-4-(5-methyl-1H-pyrazol-3-ylamino)quinazolin-2-yl)(4-fluorophenyl)methanone was prepared from (4-chloro-6-fluoroquinazolin-2-yl)(4-fluorophenyl)methanone (306 mg, 1 mmol) and 5-methyl-1H-pyrazol-3-amine (194 mg, 2 mmol) using a procedure analogous to that described in Example 48 Step A. The crude product was triturated with MeOH to afford (6-fluoro-4-(5-methyl-1H-pyrazol-3-ylamino)quinazolin-2-yl)(4-fluorophenyl)methanone (310 mg, 85%). 1H NMR (300 MHz, DMSO-d6) δ 12.24 (s, 1H), 10.71 (s, 1H), 8.64 (d, J=9.6 Hz, 1H), 7.95-8.09 (m, 2H), 7.93-7.95 (m, 1H), 7.80-7.86 (m, 1H), 7.39 (t, J=8.6 Hz, 2H), 6.53 (s, 1H), 1.91 (s, 3H); LC-MS (ESI) m/z 366 (M+H)+.
