Arylsulfonylation of 1-acetyl-3,5-diamino-1,2,4-triazole with arylsulfonyl chlorides in pyridine, with the subsequent hydrolysis of the acetyl group, was studied; a new regioselective method for synthesis of N-(5-amino-1H-1,2,4- triazol-3-yl)arylsulfonami

A new simple and efficient procedure was designed for the regiospecific preparation of arenesulfonamide derivatives of 3,5-diamino-1,2,4-triazole 1 which are precursors of N-([1,2,4] triazolo [1,5-a]pyrimidin-2-yl)arenesulfonamides 2, an important family of herbicidal and antibacterial agents. The key feature of this procedure is the preparation of a wide range of compounds 1 on a large scale, in pure form and high yield without the need for any workup or the use of the highly hazardous hydrazine. This was made possible by a novel tandem reaction promoted by sulfuryl chloride to effect the formation of the triazole ring.

Condensation of the S,S-dimethyl N-(alkylsulfonyl)carbondithioimidates 1 with aminoguanidine bicarbonate and hydrazinecarbothioamide leads to the regiospecific synthesis of N-sulfonyl derivatives of 3,5-diamino-1H-1,2,4-triazole 2 and 2,5-diamino-1,3,4-thiadiazole 3, respectively.
