Procedure

6,7-Dimethoxy-4-(3-methoxy-4-nitrophenoxy)quinoline was hydrogenated in EtOH/DMF using 10% Pd/C at 40 psi to yield 4-(6,7-dimethoxyquinolin-4-yloxy)-2-methoxy-phenylamine LCMS m/z=327 (M+1); 1H NMR (DMSO) δ: 8.43 (d, 1H, J=6 Hz), 7.5 (s, 1H), 7.37 (s, 1H), 6.76 (d, 1H, J=2.6 Hz), 6.72 (d, 1H, J=9 Hz), 6.60 (dd, 1H, J=2.5, 8.5 Hz), 6.41 (d, 1H, J=5.6 Hz), 3.75 (s, 3H), 3.31 (s, 6H). 1-Ethyl-3-(4-fluorophenyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid [4-(6,7-dimethoxy-quinolin-4-yloxy)-2-methoxyphenyl]-amide. This compound was synthesized using 4-(6,7-dimethoxyquinolin-4-yloxy)-2-methoxy-phenylamine and 1-ethyl-3-(4-fluorophenyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid using the procedure for example 1. LCMS m/z=587 (M+1); 1H NMR (CDCl3) δ: 11 (s, 1H), 8.63 (s, 1H), 8.54 (d, 1H, J=9 Hz), 8.49 (d, 1H, J=5 Hz), 7.55 (s, 1H), 7.42 (s, 1H), 7.26-7.23 (m, 3H), 6.82 (dd, 1H, J=3, 9 Hz), 6.74 (d, 1H, J=3 Hz), 6.52 (d, 1H, J=6 Hz), 4.05 (d, 6H), 4.01 (q, 2H, J=8 Hz), 3.85 (s, 3H), 1.45 (t, 3H, J=8 Hz).
