Reaction Steps
4-[2-(4-Bromo-5-chloro-thiophen-2-yl)-quinolin-3-yloxy]-6,7-dimethoxy-quinoline (20 mg) was dissolved in dioxane (3 ml) to prepare a solution. Tetrakistriphenylphosphine palladium (25 mg), methylboronic acid (0.1 ml), water (0.3 ml), and cesium carbonate (182 mg) were added to the solution, and the mixture was stirred at 100° C. for 4 days. The reaction solution was filtered, and the solvent was removed by distillation under the reduced pressure. The residue was purified by thin layer chromatography using methanol-chloroform to give the title compound (13 mg, yield 76%).
