PROCEDURE
实验过程
2-methoxyethylamine (137 μl, 1573 μmol) was added to a suspension of N-(5-(6,7-dimethoxyquinolin-4-yloxy)pyridin-2-yl)-4-iodo-2-oxo-1-phenyl-1,2-dihydropyridine-3-carboxamide (122 mg, 197 μmol) in iso-propanol (1 mL). The reaction mixture was heated at 100° C. for 80 min. An aliquot was taken and analyzed by LCMS: The reaction was done. The reaction mixture was diluted with dichloromethane. The crude was adsorbed on silica and purified by MPLC (CH2Cl2/MeOH: 100/0 to 95/5) to afford the title compound N-(5-(6,7-dimethoxyquinolin-4-yloxy)pyridin-2-yl)-4-(2-methoxyethylamino)-2-oxo-1-phenyl-1,2-dihydropyridine-3-carboxamide (84 mg, 148 μmol, 75% yield). MS (ESI pos. ion) m/z: 568 (MH+). Calc'd exact mass for C31H29N5O6: 567. 1H NMR (400 MHz, DMSO-d6) 13.28 (s, 1 H), 10.80-10.71 (m, 1 H), 8.49 (d, J=5.2 Hz, 1 H), 8.34 (d, J=9.1 Hz, 1 H), 8.30 (d, J=2.8 Hz, 1 H), 7.79 (dd, J=9.2, 3.1 Hz, 1 H), 7.73 (d, J=7.8 Hz, 1 H), 7.58-7.37 (m, 7 H), 6.53 (d, J=5.2 Hz, 1 H), 6.32 (d, J=8.1 Hz, 1 H), 3.95 (s, 3 H), 3.94 (s, 3 H), 3.64-3.54 (m, 4 H), 3.34 (s, 3 H).
