Abstract

N-(5,7-dimethoxy[1,2,4]triazolo[1,5-a]pyrimidin-2-yl) arylsulfonamide compounds were prepared from 2-amino-5,7-dimethoxy[1,2,4]triazolopyrimidine and appropriately substituted benzenesulfonyl chloride and pyridinesulfonyl chloride compounds. The compounds were found to be useful as herbicides.
