[4-(7-Benzyloxy-6-methoxy-4-quinolyloxy)phenyl](4-tert-butylphenyl)amine (starting compound 2) (400 mg) was dissolved in N,N-dimethylformamide (10 ml) to prepare a solution. Triethylamine (2 ml) and 20% palladium hydroxide (0.58 g) were then added to the solution, and the mixture was stirred in a hydrogen atmosphere at room temperature overnight. The insolubles were removed by filtration, and the solvent was then removed by evaporation under the reduced pressure. Water and ethyl acetate were added to the crude, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and was dried over sodium sulfate. The solvent was removed by evaporation under the reduced pressure, and the residue was purified by chromatography on silica gel using chloroform/acetone for development to give the title compound (205 mg, yield 62%).
