Reaction Steps
A mixture of 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinoline (500 mg, 1.7 mmol), potassium carbonate (232 mg, 1.7 mmol) and 2-bromoethanol (1181l, 1.7 mmol) in DMF (15 ml) was heated at 80° C. for 5 hours. The mixture was allowed to cool, was diluted with water and extracted with ethyl acetate. The combined extracts were washed with water, dried (MgSO4) and the solvent removed by evaporation. The residue was purified by column chromatography eluting with methylene chloride/methanol (100/0 increasing to 95/5) to give 4-(4-chloro-2-fluoroanilino)-7-(2-hydroxyethoxy)-6-methoxyquinoline (160 mg, 26%).
