ABSTRACT:
5-Amino-1,2,4-triazole-3-sulfonamides, which are intermediates for substituted 1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide herbicides are prepared in two steps from 5-amino-3-mercapto-1,2,4-triazole by chlorination in a medium containing an aqueous acid to obtain 5-amino-3-chlorosulfonyl-1,2,4-triazole and subsequent condensation of this intermediate with substituted anilines. The condensation reaction takes place either in the presence or absence of an acid scavenging base.
