Procedure

6,7-Dimethoxy-4-(4-aminophenoxy)quinoline (53 mg) was dissolved in toluene (5 ml) with heat, after the addition of triethylamine (1 ml), triphosgene (101 mg) was added, and the admixture was ref luxed with heat for 4 minutes. 3,5-Dimethoxyaniline (62 mg) was added to the reaction mixture, and the admixture was refluxed with heat for 13 minutes. After the addition of aqueous sodium hydrogen carbonate, the reaction mixture was extracted 2 times with ethyl acetate, and the organic layer was then washed with brine and 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 (10/1) to obtain 85 mg of the title compound (yield: 100%)).
