Synthesis and spectral properties of novel thiadiazolotriazinone derivatives

Abstract

A series of new 7-substitued-4H-1,3,4-thiadiazolo[2,3-c][1,2,4]- triazin-4-oneswere synthesized in good yields by the reaction of 4-amino-3- mercapto-1,2,4-triazin-5(4H)-one with various aromatic carboxylic acids in the presence of phosphorus oxychloride. All the synthesized compounds were confirmed by FT-IR, NMR (1H and 13C), ESI-MS spectroscopic techniques and analytical methods.
