Abstract
Substituted N-pyridinyl[1,2,4]triazolo[1,5-c]-pyrimidine-2-sulfonamide compounds, such as N-(2-fluoro-4-methyl)-7-fluoro-5-methoxy[1,2,4]triazolo[1,5-c]pyrimidine-2 -sulfonamide, were prepared by condensation of a 2-chlorosulfonyl[1,2,4]triazolo[1,5-c]pyrimidine compound, such as 2-chlorosulfonyl-7-fluoro-5-methoxy[1,2,4]triazolo[1,5-c]pyrimidine, with a substituted 3-aminopyridine compound, such as 3-amino-2-fluoro-4-methylpyridine, and found to possess herbicidal utility.
