Versuchsvorschrift

A mixture of N-(4-((2-chloropyridin-4-yl)oxy)-2,5-difluorophenyl)-4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (0.100 g, 0.194 mmol, see: Example 1), cyclopropanecarboxamide (0.033 g, 0.388 mmol), Cs2CO3 (0.095 g, 0.291 mmol) and Xantphos (5.05 mg, 8.72 μmmol) in dioxane (2 mL) was sparged with argon, treated with Pd2(dba)3 (2.66 mg, 2.91 μmmol), sparged again with argon, then fitted with a reflux condensor capped with an argon-filled balloon and heated to 100° C. overnight. The mixture was cooled to RT and partitioned between water and EtOAc. The organic layer was washed with brine, dried over MgSO4, concentrated to dryness and purified via silica gel chromatography (EtOAc/Hex) to afford N-(4-((2-(cyclopropanecarboxamido)pyridin-4-yl)oxy)-2,5-difluorophenyl)-4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (33 mg, 30% yield) as a solid. MS (ESI) m/z: 565.2 (M+H+).
