CuI/4-hydroxy-l-proline catalyzed coupling of N-substituted o-bromobenzamides with formamide takes place at 80 °C, affording 3-substituted quinazolinones directly. Under these conditions other amides that were tested only provided simple coupling products, which can be converted into 2,3-disubstituted quinazolinones via HMDS/ZnCl2 mediated condensative cyclization.
