Some of Schiff base derivatives were separated by condensing 3-formyl-2-quinolinone with various primary amine derivatives in ethanol, in which water is expelled. Moreover, substituted acryloylphenyliminomethylquinolinone chalcone derivatives were prepared by the process of condensation reaction of aldehyde derivatives with 3-acetylphenylquinolinone in dilute solution of ethanolic sodium hydroxide...
