coupling of 2-aminobenzamides 1 and isocyanides 2 mediated by I2 and cumylhydroperoxide (CHP) leads to the formation of 2-aminoquinazolinones 3 in moderate to excellent yields. This method provides an efficient approach to 2-aminoquinazolinones with high atom economy under metal-free conditions through two C–N bond-formation reactions. The products can be further transformed to give benzo[4,5]imidazo[2
