Participants

Reaction Steps

6,7-Dimethoxy-4-(4-aminophenoxy)quinazoline (100 mg) was dissolved in toluene (10 ml) with heat, 3-methoxyphenyl isocyanate (0.36 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/methanol (100/1) and then with chloroform/acetone (5/1) to obtain 31 mg of the title compound (yield: 21%).
