Abstract

2-Substituted 4-(arylamino)quinazolines were prepared from 2-(acylamino)benzonitriles and primary arylamines by refluxing in either ethanol using trifluoroacetic acid as a catalyst or acetic acid. The 2-aminobenzonitrile was acylated by reaction with anhydrides, isocyanates, or ethyl chloroformate at room temperature.
