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.

Heterocyclic Derivatives

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).

Molecular Weights

This study including prepared new colored esters containing heterocyclic with high molecular weights. In the first part of work we synthesized azo dyes [1,2] from the reaction p-toluidine with β-naphthol and o-nitro phenol, thin we synthesized Schiff bases [3,4] by the reaction anthranilic acid with benzaldehyde and dimethyl benzaldehyde. The reaction azo dyes (contain OH group) with Schiff base (contain COOH group) these led to produce the new colored esters [A1-A4]. The second part of work was modification the (C=N-) group in esters to heterocyclic compounds by reacting with phenyl iso cyanide to produce new β-lactam [B1-B4] and with anthranilic acid to get new hydroquinazoline [C1-C4]. All these compounds were characterized by physical properties and spectral methods FTIR, 1H-NMR and 13C-NMR.
