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 including1H and13C NMR spectroscopy, IR spectroscopy, mass spectrometry, and elemental analysis. The fastness properties and UV/Vis absorption spectroscopic data of these disperse dyes in printing polyester fabrics were investigated.
