3,5-Dimethyl-1-phenyl-1H-pyrazolooxazole 5 was prepared and used as starting material in the synthesis of some polymethine cyanine dyes incorporating a biheterocyclic system.The chemical structure of the new polymethine cyanines were identified based on their elemental analysis and spectral data.The electronic absorption spectra of the synthesized cyanine dyes are discussed.
