This work has been carried out to investigate the synthetic approaches of different six series of new heterocyclic azo - dyes via conventional refluxing and microwave heating.As from a sequence of reactions starting from cyanoacetic acid , 4 - arylazo - 2H - pyrazol - 3 - ylamines are obtained.The produced pyrazoles give on cyclization with 3 - piperidinoacrylonitrile , ethyl acetoacetate , ethyl arylhydrazono - acetoacetates and arylhydrazono - propanals , different derivatives of arylazo - pyrazolo[1 , 5 - a]pyrimidines and pyrazolo[1 , 5 - a]pyrimidin - 7 - ones.Structures of the obtained compounds were established with certainty via inspection of spectroscopic and analytical data.Evaluation of fastness properties and spectral data of these different series of new disperse dyes in printing
