A series of 4(3H)-quinazolinones 3 were obtained from the one-pot synthesis of available substituted aromatic o-aminonitriles 1 with aldehydes 2 in the present of base. This tandem transformation was included in addition, intramolecular Pinner reaction, Dimroth rearrangement and oxidative dehydrogenation. The structures of products were characterized by 1H NMR, 13C NMR, IR spectra and elemental analysis.

Key words: one-pot synthesis, aromatic o-aminonitrile, aldehyde, base catalysis, 4(3H)-quinazolinone
