Various of 2,5- disubstituted 1,3,4-oxadiazole (Schiff base, ?- lactam and azo) were synthesized from 2,5-di (4,4?-amino-1,3,4-oxadiazole which usequently synth-esized from mixture of 4- amino benzoic acid and hydrazine arch of polyphosphorus acid. The synthesized compounds were cherecterized by using some spectral data (UV, FT-IR , and 1H-NMR)

This study involves a synthesis of some formazan derivatives starting from react chloro acetyl chlorid with 2-amino-4-hydroxy-6-methyl pyrimidine to gate compound (a), (a) react with hydrazine hydrate to give compound (b) also (b) react with 3-4-dimethoxy benzaldehyd to product Schiff base derivative (c) then (c) react with deferent amin derivatives to get formazan derivatives. All these compounds characterized by 13C-NMR, fourier transform infrared spectroscopy (FTIR), 1HMNR. After that, we study the biological activity for all formazan derivatives toward two different kinds of bacteria and anti-cancer.

Introduction: In this work synthesis, many kinds of heterocyclic derivatives by many steps, the first we preparation 1-(4-((1H-imidazol_2-yl-) diazenyl) phenyl) ethan-1_one. (1) by coupling of diazonium salt of p-amino acetophenone with imidazole in alkaline alcoholic media, the second step include react (1) with 2_amino_6_methylpyrimidin _4_ol in acid medium to get Schiff base derivatives(2)the last step include react(2) with (sodium azide, thioglycolic acid, glycine, alanine, Tryptophan, (2 aminobenzoic acid), (2-mercaptobenzoic acid) to give (tetrazole(3), thiazolidine(4), imidazolidine(5-7), Thiazinie(8), Quinazoline (9) derivatives, respectively. All these derivatives Characterization by FTIR, 1HNMR, 13C-NMR, After that we studied the biological activity for all derivatives for all derivatives studied the anticancer for (2).

In this research various of 2,5-disubstituted 1,3,4-oxadiazole (Schiff base, oxo-thiazolidine , and other compounds) were synthesized from 2,5-di(4,4?- amino-1,3,4-oxadiazole ) which use quently synthesized from mixture of 4-amino benzoic acid and hydrazine in the presence of polyphosphorus acid. The synthesized compounds were characterized by using some Spectral data (UV, FT-IR, and 1H-NMR).
