| Abstract | ||
| New series of 2-hydrazinyl-3H-imidazol[4,5b]pyridine derivatives were prepared by reacting the 2-mercapto-3H-imidazol[4-5b]pyridine A with hydrazine hydrate give compound( 1), which reacted with aromatic aldehyde, benzyl, nitrous acid, ethyl cyanoacetae, acetylaceton, formic acid, benzoylchloride, chloroaceticacid , benzalacetophenon and Glucose, to give new derivatives of pyrazoline, traizine, triazole and tetrazole, compounds (2-11), some new N(5-(aryl phenyl)-H-tetrazol -yl) -3H-imidzo[4,5b]pyridine-2-amine,derivatives (12a,b-14a,b) have been prepared by reaction of 2-hydrazinyl -3H-imidazo [4,5b] pyridine (1) with various aromatic acid chloride and sodium azide., the prepared compounds were confirmed by techniques FT-IR spectrum and Elemental Analysis and some of them confirmed by 1HNMR spectrum. | ||
