Reaction Steps
4-[2-(5-Chloro-4-methyl-thiophen-2-yl)-quinolin-3-yloxy]-6,7-dimethoxy-quinoline (compound 290) (7 mg) was dissolved in triethylamine/N,N-dimethylformamide (0.5 ml/1.5 ml) to prepare a solution, 20% palladium hydroxide (68 mg) was added to the solution, and the mixture was stirred under a hydrogen gas atmosphere at room temperature overnight. The reaction solution was filtered, and the solvent was then removed by distillation under the reduced pressure. Water was 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 sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by thin layer chromatography using acetone-chloroform to give the title compound (3.6 mg, yield 56%).
