2-aminoquinazolinones derivatives from inexpensive reactants. A simple and efficient method was developed for the synthesis of N-aroyl-N′-arylguanidines under mild conditions by an unexpected demethylation–addition cascade reaction of readily available N-cyanoimidates with aryl amines. Moreover, 1-aryl-2-aminoquinazolin-4(1H)-ones and 2-(arylamino)quinazolin-4(3H)-ones can also be prepared by selective cyclization
