A series of 2-substituted-4(3H)-quinazolinones 13-20 has been synthesized in good yields using the reaction of double lithiated 2-methylquinazolinone-4 with a variety of aromatic aldehydes. They have been easily transformed in high yields into the corresponding 2-substituted conjugated derivatives 21-28 bearing terminal aryl groups by F3CCOOH mediated dehydration.
