Abstract The reaction of N-aryl benzamidines with diphenyl carbonate or ethyl phenyl carbonate synthesized 2-arylquinazolin-4 (3H)-ones in simple and safe process with good yields (71–90%). It was suggested that different electron-donating substituent in N-aryl benzamidines afforded similar effect to the yields of 2-arylquinazolin-4 (3H)-ones. In these reactions, N-aryl benzamidines built up intermediate compounds by nucleophilic addition ...
