Participants

Reaction Steps

6,7-Dimethoxy-4-(4-aminophenoxy)quinazoline (100 mg) was dissolved in toluene (10 ml) with heat, n-butyl isocyanate (0.29 ml) was added, and the admixture was refluxed with heat for 40 minutes. After removing the solvent by distillation, the resulting residue was purified by column chromatography on silica gel eluting with chloroform/acetone (5/1) to obtain 75 mg of the title compound (yield: 56%).
