6,7-Dimethoxy-4-(4-aminophenoxy)quinoline (52 mg) was suspended in triethylamine/methylene chloride (3 ml/2 ml), commercially available biphenylcarbonyl chloride (80 mg) was added, and the admixture was stirred at room temperature for 25 hours. Aqueous sodium hydrogen carbonate was added to the reaction mixture, and the resulting admixture was extracted with ethyl acetate. The ethyl acetate layer was washed with brine and then dried with anhydrous sodium sulfate. The solvent was removed by reduced-pressure distillation, and the resulting residue was purified by column chromatography on silica gel eluting with chloroform/acetone and further by washing resulting crystals with acetoneto obtain 9 mg of the title compound (yield: 10%).
