Synthesis of Some Novel Benzotriazole-1-yl-acetic acid substituted aryl hydrazide Derivatives as Anticonvulsant Agents
Subscribe/Renew Journal
Benzotriazole (I) has been prepared by reacting ortho phenylene diamine with Sodium nitrite in presence of glacial acetic acid at 850 OC. N1-ethylacetate derivative of Benzotriazole (II) was synthesized by reacting the Benzotriazole (I) with ethyl chloroacetate in dry acetone solvent and in presence of anhydrous Potassium carbonate. N-Hydrazine hydrate derivative of Benzotriazole (III) were synthesized by reacting the ethylacetate derivative of Benzotriazole with hydrazine hydrate. Newly synthesized Benzotriazole derivatives of Aromatic Aldehydes (IVc,d) and aromatic ketones (IVa,b ) were prepared by reacting the Hydrazine hydrate derivative of Benzotriazole with 4-OH Benzaldehyde, N, N - dimethyl amino Benzaldehyde, Acetophenone and benzophenone in methanol and these synthesized compounds were confirmed by IR and NMR spectras. Which were purified by recrystallisation and column chromatography. The conformed compounds were evaluated for anticonvulsant activity using phenytoin as standard by MES method.
