Procedure

1-[2-(6,7-Dimethoxy-quinolin-4-yloxy)-5-hydroxy-phenyl]-ethanone (compound 176) (75 mg) was dissolved in N,N-dimethylformamide (2 ml) to prepare a solution. Ethyl iodide (103 mg) and potassium carbonate (153 mg) were added to the solution, and the mixture was stirred at room temperature overnight. The solvent was removed by distillation under the reduced pressure, water was then added to the residue, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was then washed with water and was dried over anhydrous magnesium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by thin layer chromatography using acetone-hexane to give the title compound (50 mg, yield 62%).
