Background: Pyrazole is a simple aromatic ring an organic compound of the heterocyclic series that characterized five-membered ring structure which comprises located adjacent two nitrogen atoms and three carbon atoms. In recent years interest in the pyrazole chemistry excessively has increased due to many a wide range of properties. Because they have a wide range of specific properties such as biological activities, pharmaceutical i.e., Pyrazoles were also applied successfully in many fields; medicine, agricultural, industry, pharmaceutical chemistry so that pyrazole chemistry was quite an interesting area of research for the synthesis of their derivatives and investigates new methods.
