摘要：
Substituted ring annulated 5-alkoxy-N-aryl-[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide compounds, such as N-(2,6-dichlorophenyl)-5-methoxycyclopenteno[d]-[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide, were prepared by condensation of an appropriate 2-chloro-sulfonyl-5-alkoxy[1,2,4]triazolo[1,5-c]pyrimidine compound, such as 2-chlorosulfonyl-5-methoxycyclopenteno[d][1,2,4]triazolo[1,5-c]pyrimidine, with a substituted arylamine compound, such as 2,6-dichloroaniline, and found to possess herbicidal utility.
