Phenyl isocyanate → N-{4-[(6,7-Dimethoxy-4-quinolyl)oxy]phenyl}-N'-phenylurea

Participants

Reaction Steps

6,7-Dimethoxy-4-(4-aminophenoxy)quinoline (51 mg) was dissolved in toluene (5 ml) with heat, phenyl isocyanate (0.2 ml) was added, and the admixture was refluxed with heat for 50 minutes. The resulting residue was purified by column chromatography on silica gel eluting with chloroform/acetone (10/1) to obtain 21 mg of the title compound (yield: 41%).
