Procedure

Propyl 3-(7-hydroxy-6-methoxy-quinolin-4-yloxy)-naphthalene-2-carboxylate (80 mg) and 1-bromo-2-chloroethane (0.082 ml) were dissolved in N,N-dimethylformamide (2 ml) to prepare a solution. Potassium carbonate (274 mg) was added to the solution, and the mixture was stirred at room temperature overnight. Water was then added to the reaction solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was then washed with saturated brine and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using acetone-chloroform to give the title compound (85 mg, yield 91%).
