ABSTRACT 2-Hydrazinyl-pyrido[3′,2′:4,5]thieno[3,2-d]pyrimidin-4(3H)-one was reacted with commercially available active methylene compounds (e.g., acetylacetone, ethyl acetoacetate, and diethyl malonate) and ethoxymethylenemalononitrile to afford the respective pyrazole derivatives. Moreover, the prepared pyrazolinone was utilized for synthesis of some new arylidene-, arylazo-pyrazolinone, and azolo-triazine derivatives. The structures of the synthesized compounds were assigned on the basis of elemental analysis, IR, 1H NMR, and mass spectral data. GRAPHICAL ABSTRACT
