4-Acetylphenyl isocyanate → N-(4-Acetylphenyl)-N'-{4-[(6,7-dimethoxy-4-quinolinyl)oxy]phenyl}urea

Participants

Reaction Steps

6,7-Dimethoxy-4-(4-aminophenoxy)quinoline (51 mg) was dissolved in toluene (3 ml) with heat, 4-acetylphenyl isocyanate (210 mg) was added, and the admixture was refluxed with heat for 20 minutes. The resulting residue was purified by column chromatography on silica gel eluting with chloroform/acetone (10/1) to obtain 50 mg of the title compound (yield: 64%).
