Propyl 3-[7-(2-chloro-ethoxy)-6-methoxy-quinolin-4-yloxy]-naphthalene-2-carboxylate (compound 322) (138 mg) was dissolved in N,N-dimethylformamide (2 ml) to prepare a solution. Potassium carbonate (274 mg) and imidazole (101 mg) were added to the solution, and the mixture was stirred at 60° C. overnight. Water was 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 pufified by thin layer chromatography using chloroform-methanol to give the title compound (105 mg, yield 70%).
