Palladium acetate (18 mg) and (+)-BINAP (70 mg) were dissolved in toluene (1.5 ml), and the solution was stirred at room temperature for 5 min. (4-Bromophenyl)-[4-(6,7-dimethoxy-4-quinolyloxy)phenyl]amine (100 mg), morpholine (0.15 ml), and cesium carbonate (200 mg) were added in that order to the reaction solution, and the mixture was stirred at 80° C. overnight. The insolubles were removed by filtration, and the solvent was then removed by evaporation under the reduced pressure. The residue was purified by thin-layer chromatography on silica gel using chloroform/acetone to give the title compound (10 mg, yield 9%).
