摘　　要：Carbon-based solid acid catalyst has been applied to catalyzing the synthesis of 4（3H）-quinazolinones from the cyclization reaction of 2-aminobenzamide with aroyl chlorides. The results showed that the catalyst was very efficient with the average yield over 85%. This carbon material with strong protonic acid sites as heterogeneous cata- lyst has some advantages such as high activity, strikingly simple work-up procedure, non-pollution, and reusability, which will contribute to the green process greatly.Carbon-based solid acid catalyst has been applied to catalyzing the synthesis of 4（3H）-quinazolinones from the cyclization reaction of 2-aminobenzamide with aroyl chlorides.
