A simple and convenient synthesis of 5-amino-substituted tetrazolo[1,5-a]-1,3,5-triazin-7-one salts

A simple and convenient three-step synthesis of 5-amino-substituted tetrazolo[1,5-a]-1,3,5-triazin-7-one sodium salts based on a fairly simple sequence of nucleophilic substitution of chlorine atoms in cyanuric chloride has been developed. The corresponding tetrabutylammonium salts were synthesized by cation-exchange with tetrabutylammonium chloride. The structures of the products were characterized by IR, 1H NMR and 13C NMR spectroscopy, and by elemental and X-ray analysis.
