Procedure

6,7-Dimethoxy-4-(4-aminophenoxy)quinoline (51 mg) was dissolved in toluene (5 ml) with heat, 4-ethylphenyl isocyanate (0.2 ml) was added, and the admixture was refluxed with heat for 90 minutes. The resulting residue was purified by column chromatography on silica gel eluting with chloroform/acetone (10/1) to obtain 42 mg of the title compound (yield: 56%).
