5-Acylamino-1,2,4-triazole-3-sulfonamides, which are useful intermediates for the preparation of 1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide herbicides are prepared from 5-amino-3-mercapto-1,2,4-triazole by sequential acylation to 5-acylamino-3-mercapto-1,2,4-triazoles, chlorination to 5-acylamino-3-chlorosulfonyl-1,2,4-triazoles, and condensation with substituted anilines to 5-acylamino-1,2,4-triazole-3-sulfonamides. 5-Acylamino-3-chlorosulfonyl-1,2,4-triazole compounds are key intermediates in the process.
