5-Amino-3-chlorosulfonyl-1,2,4-triazole is prepared by the chlor-oxidation of 5-amino-3-mercapto-1,2,4-triazole. The process is characterized by the preformation of disulfide from the mercaptan prior to treatment with chlorine. The 5-amino-3-chlorosulfonyl-1,2,4-triazole reaction mixture can be directly reacted with substituted anilines to prepare N-(3-(((aryl)amino)sulfonyl)-1H-1,2,4-triazol-5-yl)amines which are useful intermediates for the manufacture of herbicides. |
