Reaction Steps

4-Anilino-2-{4-[2-hydroxy-3-(N,N-dimethylamino)propoxy]anilino}-5-nitropyrimidine (Example 20, 400 mg, 0.90 mmol) was dissolved in ethanol (20 ml). Under an atmosphere of nitrogen, cyclohexene (5 ml) was added followed by 10% palladium-on-carbon (100 mg). The mixture was heated under reflux for 5 hours, and then a further portion of 10% palladium on carbon (100 mg) was added and heating was continued for 18 hours. The catalyst was removed by filtration through diatomaceous earth and the filtrate was concentrated by evaporation. The resulting oil was purified by column chromatography, eluting with 0-10% 2.0M methanolic ammonia in DCM to give the product as a white solid (300 mg, 80%). NMR: 2.15 (s, 6H), 2.3 (m, 2H), 3.8 (m, 3H), 4.3 (s, 2H), 4.7 (s, 1H), 6.8 (d, 2H), 7.0 (t, 1H), 7.3 (t, 2H), 7.5 (d, 2H), 7.6 (s, 1H), 7.8 (d, 2H), 8.1 (s, 1H), 8.4 (s, 1H); MS (MH+): 395.
