To a mixture of 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (74 mg, 0.32 mmol), HOBt (16 mg) and EDCI.HCl (65 mg, 0.34 mmol) in DMF (3 mL) was added a solution of 4-(6,7-dimethoxyquinolin-4-yloxy)-3-fluorobenzenamine (120 mg, 0.31 mmol) in DMF (3 mL) at rt, and the reaction mixture was stirred overnight at rt. It was directly purified by preparative HPLC to afford the product (46 mg, 20%) as a white TFA salt solid. 1H NMR (DMF-d7) δ 12.22 (s, 1H), 8.71 (d, 1H, J=6.0 Hz), 8.59 (d, 1H, J=7.2 Hz), 8.14-7.31 (m, 15H), 6.84 (d, 1H, J=5.5 Hz), 6.72 (t, 1H, J=7.2 Hz), 5.35 (s, 2H), 4.02 (s, 3H); MS(ESI+) m/z 606.3 (M+H)+.
