Procedure
To a mixture of 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (15 mg, 0.06 mmol), HOBt (10 mg) and EDCI.HCl (20 mg, 0.10 mmol) in DMF (2 mL) was added a solution of tert-butyl 4-((4-(4-amino-2-fluorophenoxy)-6-methoxyquinolin-7-yloxy)methyl)piperidine-1-carboxylate (35 mg, 0.07 mmol) in DMF (1 mL) at rt, and the reaction mixture was stirred overnight at rt. It was directly purified by preparative HPLC to afford the product (24 mg, 56%) as a white TFA salt solid. 1H NMR (CDCl3) δ 12.16 (s, 1H), 8.75 (d, 1H, J=7.7 Hz), 8.64 (d, 1H, J=5.5 Hz), 8.05 (d, 1H, J=12.1 Hz), 7.83 (s, 1H), 7.67-7.24 (m, 8H), 6.72 (d, 1H, J=6.1 Hz), 6.65 (t, 1H, J=6.6 Hz), 4.22-4.11 (m, 2H), 4.07 (s, 3H), 3.48 (s, 2H), 2.78 (m, 2H), 2.13 (m, 1H), 1.87 (m, 2H), 1.47 (s, 9H), 1.35 (m, 2H).
