Reaction Steps

4-Chloro-6,7-dimethoxyquinoline (WO 98/13350 A1) (150 mg) and N-(3-amino-4-methylphenyl)-3-dimethylaminobenzamide (199 mg) were stirred in isopropanol (5 ml) and heated to 85° C. for 18 hours. After cooling to room temperature the precipitated solid was isolated and washed with isohexane. Filtered solid was impure and so was purified by eluting through a silica column with 10% methanol in methylene chloride. The title compound was obtained as a solid (35 mg); NMR: 2.14 (s, 3H), 2.94 (s, 6H), 3.89 (s, 3H), 3.93 (s, 3H), 6.05 (m, 1H), 6.90 (m, 1H), 7.18 (m, 1H), 7.22 (m, 1H), 7.3 (m, 1H), 7.61 (m, 1H), 7.73 (s, 1H), 7.78 (m, 1H), 8.18 (d, 1H), 8.47 (s, 1H), 10.1 (s, 1H); m/s: M+H+ 457.
