Procedure

To a solution of 4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonyl chloride (0.275 g, 0.929 mmol) in CH2Cl2 (2 mL) was added a suspension of 5-chloro-2-fluoro-4-(3-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yloxy)benzenamine (0.148 g, 0.464 mmol) in pyridine (2.00 mL) at 0° C. The resultant mixture was stirred at ambient temp for 30 min. The solvent was completely evaporated and the residue was stirred in water. The precipitate was collected by filtration and was re-crystallized from acetonitrile to provide N-(5-chloro-2-fluoro-4-(3-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yloxy)phenyl)-4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (0.101 g, 37.6% yield) as an off-white solid. The mesylate salt was prepared by treatment with one equivalent of methanesulfonic acid. 1H NMR (400 MHz, DMSO-d6) δ 11.40 (s, 1H), 9.20 (s, 1H), 8.62 (d, J=5.5 Hz, 1H), 8.51 (m, 1H), 8.47 (s, 1H), 8.23 (s, 1H), 8.00 (d, J=8.0 Hz, 1H), 7.75 (d, J=11 Hz, 1H), 7.50 (m, 2H), 7.41 (m, 2H), 7.25 (d, J=2.5 Hz, 1H), 6.60 (d, J=5.5 Hz, 1H), 4.30 (q, J=6 Hz, 2H), 3.92 (s, 3H), 2.30 (s, 3H), 1.30 (t, J=6 Hz, 3H); MS (ESI) m/z: 578.2 (M+H+).
