<p>Substitued N-pyridinyl[1, 2, 4]triazolo[1, 5-c]pyrimidine -2-sulfonamide compounds of formula (I), 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 possesss herbicidal utility.</p> |
