Reaction Steps

Propyl 3-[7-(2-chloro-ethoxy)-6-methoxy-quinolin-4-yloxy]-naphthalene-2-carboxylate (compound 322) (80 mg) was dissolved in N,N-dimethylformamide (2 ml) to prepare a solution. Potassium carbonate (484 mg) and morpholine (0.15 ml) were added to the solution, and the mixture was stirred at 60° C. for 2 days. The reaction solution was cooled to room temperature, water was then added thereto, 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 thin layer chromatography using hexane-acetone to give the title compound (52 mg, yield 59%).
