실험 절차

A solution of Example A2 (0.100 g, 0.332 mmol) in THF (1 mL) was treated with triethylamine (0.069 ml, 0.498 mmol) and a suspension of 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonyl chloride (0.125 g, 0.498 mmol) in THF (2 mL). The mixture was blanketed with argon and stirred overnight at room temperature. The solids were removed via filtration, rinsed with THF and the filtrate was concentrated to dryness. The crude material was purified by silica gel chromatography (10-100% EtOAc/Hex) to afford N-(4-(3-bromopyridin-4-yloxy)-2,5-difluorophenyl)-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (122 mg, 71% yield) as a pale yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 12.45 (s, 1H); 8.74 (s, 1H); 8.58 (m, 2H); 8.38 (d, J=5.6 Hz, 1H); 8.15 (dd, J=6.6, 2.2 Hz, 1H); 7.67 (dd, J=11.0, 7.3 Hz, 1H); 7.60 (dd, J=8.8, 4.9 Hz, 2H); 7.41 (t, J=8.7 Hz, 2H); 6.89 (d, J=5.6 Hz, 1H); 6.74 (t, J=7.0 Hz, 1H); MS (ESI) m/z: 516.0, 518.0 (M+H+).
