Abstract
2-Methyl-3,1-benzoxazine-4-one (3), generated by cyclizing of N-acetyl-anthranilic acid with ethyl chloroformate in benzene containing triethyl-amine, reacts with primary amine and subsequently aromatic aldehyde when heated under reflux in glacial acetic acid to give 3-substituted 2-styryl-3,4-dihydro-4-quinazolones (7).
