Procedure

To a solution of Example A2 (29 g, 113 mmol) and triethylamine (23 g, 226 mmol) in THF (400 mL) was added freshly prepared 4-ethoxy-1-(4-fluoro-phenyl)-2-oxo-1,2-dihydro-pyridine-3-carbonyl chloride (33.5 g, 113 mmol) and the mixture was stirred at RT overnight. The mixture was concentrated in vacuo, and the residue was diluted with water (500 mL) and extracted with EtOAc (3×500 mL). The combined organics were washed with brine, dried over Na2SO4 and concentrated to afford N-(4-((2-chloropyridin-4-yl)oxy)-2,5-difluorophenyl)-4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (51 g, 87% yield).
