A method is proposed for the synthesis of ethyl 5-(3-aryl-4-formyl-1H-pyrazol-1-yl)-1,2,3-thiadiazole-4-carboxylates by a reaction of acetophenone (4-ethoxycarbonyl-1,2,3-thiadiazol-5-yl)hydrazones with a Vilsmeier–Haack complex. The obtained heterocyclic assemblies provide interesting substrates for further modification and study of biological activity.
