| Summary: | In this research the polymer which contains aldehyde group [H1] has been prepared by oxidation [H] using the oxidizing agent (Dess Martin Periodinane), [H1] has been dialyzed by ethanol, Schiff bases[H2,H5andH8] compounds have been prepared through the reaction of compound [H1] with appropriate amines, [H3] compound which contains hydroquinazolin ring has been prepared by the reaction of [H2] compound with 2-amino benzoic acid.[H4]which has been prepared by cyclization reaction of compound [H2] with phthalic anhydride. compounds [H6,H7]were prepared by the reaction of [H5] compound with 2-amino benzoic acid and phthalic acid anhydriede. Reaction of comp[H1] with 4-amino benzaldehyde afforded comp[8]. The [H9] compound prepared by the reaction of [H8] compound with thiocarbohydrazide, The structures of the synthesized compounds [1-9] have been characterized using avaible spectral ( IR, 1H-NMR) methods and the result obtained improved the structures assigned to these compounds
