Thiazoles substituted in positions 2 and 4 by hydroxy, mercapto and amino groups were synthesized, as well as its carbamate derivates and formylhydrazones.The research of the reaction of the formylhydrazide with 4-imino-2-thiazolidinone has not given the pyrazolothiazol-2-one, but the 4-formylhydrazono-2-thiazolidine.The detailed tautomeric study of each of the heterocyclic compounds has been carried out by infrared spectroscopy, nuclear magnetic resonance of proton and of 13-carbon, and of masses.
