Reaction Steps

N-(4-((2-chloropyridin-4-yl)oxy)-2,5-difluorophenyl)-5-(4-fluorophenyl)-1-methyl-4-oxo-1,4-dihydropyridine-3-carboxamide (0.125 g, 0.221 mmol) was combined with 1-methyl-pyrazole-4-boronic acid (0.058 g, 0.277 mmol) and K2CO3 (0.092 g, 0.664 mmol) in dioxane (2 mL) and H2O (0.333 mL), the mixture sparged with argon, treated with Pd(PPh3)4 (0.013 g, 0.011 mmol), sparged again with argon, and heated to 80° C. overnight. The mixture was cooled to RT, diluted with EtOAc, washed with H2O, then brine, dried over MgSO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to afford N-(2,5-difluoro-4-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)phenyl)-5-(4-fluorophenyl)-1-methyl-4-oxo-1,4-dihydropyridine-3-carboxamide (103 mg, 88%) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 13.50 (s, 1H), 8.72 (d, J=2.3 Hz, 1H), 8.57 (dd, J=12.7, 7.2 Hz, 1H), 8.37 (d, J=5.7 Hz, 1H), 8.27 (s, 1H), 8.16 (d, J=2.3 Hz, 1H), 7.98 (s, 1H), 7.70 (dd, J=8.6, 5.6 Hz, 2H), 7.58 (dd, J=11.0, 7.4 Hz, 1H), 7.30-7.22 (m, 3H), 6.74 (dd, J=5.7, 2.5 Hz, 1H), 3.92 (s, 3H), 3.84 (s, 3H); MS (ESI) m/z: 532.2 (M+H+).
