1-Hydroxybenzotriazole → N-(4-(6,7-Dimethoxyquinolin-4-yloxy)-3-fluorophenyl)-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide

Participants

Reaction Steps

To a mixture of 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (45 mg, 0.19 mmol), HOBt (20 mg) and EDCI.HCl (80 mg, 0.31 mmol) in DMF (2.5 mL) was added 4-(6,7-dimethoxyquinolin-4-yloxy)-3-fluorobenzenamine (56 mg, 0.18 mmol) at rt, and the reaction mixture was stirred over the weekend at rt. It was directly purified by preparative HPLC to afford the product (35 mg, 30%) as a beige-colored TFA salt solid. 1H NMR (CD3OD) δ 12.21 (s, 1H), 8.60 (dd, 2H, J=9.9, 1.6 Hz), 8.01 (d, 1H, J=12.6 Hz), 7.90 (dd, 1H, J=7.6, 1.6 Hz), 7.74 (s, 1H), 7.45-7.37 (m, 5H), 7.24 (t, 2H, J=8.2 Hz), 6.89 (d, 1H, J=6.6 Hz), 6.65 (t, 1H, J=6.6 Hz), 4.03 (s, 3H), 4.00 (s, 3H); MS(ESI+) m/z 530.2 (M+H)+.
