2-Amino-substituted-4(3H)-quinazolinones have been synthesized via an efficient metal-free reaction between 2-aminobenzamide derivatives and carbonimidic dibromides. The reaction proceeds in the presence of K2CO3 affording cyclized products in good to excellent yields. (C) 2015 Elsevier Ltd. All rights reserved.
