Background: Nitrogen-containing heterocyclics are abundant in natural products and also in synthetic drug molecules because of a variety of applications and superior pharmacological profile action. Pyrazoles are the integral architects of many of the heterocyclic compounds with superior biological activity. Methods: Two series of the pyrazole conjugated Benzothiazole derivatives were synthesized. The pyrazoles were synthesized by the Vilsmeier-Haack reaction and then conjugated with benzothiazole hydrazine and hydrazide by imine bond formation. The synthesized compounds were screened for anti-

In addition, aryl hydrazides can be transformed to aryl hydrazines and aryl amines, which can be further applied to synthesize heterocyclic compounds. Herein, our laboratory wish to report a novel synthetic method for preparation of aryl hydrazide from arylbromide, magnesium powder, 1,2-dibromoethane and diethyl azodicarboxylate via sonochemical Barbier-type reaction.
