The synthesis of heterocyclic azo-dyes via conventional heating and microwave (MW) heating was investigated. From a sequence of reactions starting from cyanoacetic acid, 4-arylazo-2H-pyrazol-3-ylamines and 4-arylazo-2-phenyl-2H-pyrazol-3-ylamines were obtained. The structures these compounds were obtained by inspection of spectroscopic and analytical techniques including 1H and 13C NMR spectroscopy
