실험 절차

A solution of Example A1 (0.147 g, 0.572 mmol) in THF (1 mL) was treated with Et3N (0.120 mL, 0.858 mmol) and a suspension of Example A3 (0.216 g, 0.858 mmol) in THF (2 mL). The mixture was layered with argon and stirred at RT overnight. The mixture was cooled to RT, the solid removed via filtration, rinsed with THF and the filtrate concentrated to dryness. The residue was triturated with MeCN, sonicated and the resulting solid collected via filtration and dried to afford N-(4-((2-chloropyridin-4-yl)oxy)-2,5-difluorophenyl)-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (104 mg, 38%) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 12.51 (s, 1H), 8.71-8.61 (m, 2H), 8.38 (d, J=5.8 Hz, 1H), 8.23 (dd, J=6.6, 2.2 Hz, 1H), 7.69 (m, 3H), 7.49 (m, 2H), 7.25 (d, J=2.3 Hz, 1H), 7.13 (dd, J=5.8, 2.3 Hz, 1H), 6.82 (m, 1H).
