Abstract
N-(substituted aryl)�1,2,4!triazoloazinesulfonamide compounds, such as N-(2,6-difluorophenyl)-8-fluoro-5-methoxy�1,2,4!triazolo�1,5-c!pyrimidine- 2-sulfonamide, were prepared at a good reaction rate and in good yield by the reaction of a chlorosulfonyl�1,2,4!triazoloazine compound, such as 2-chlorosulfonyl-8-fluoro-5-methoxy�1,2,4!triazolo�1,5-c!pyrimidine, and an arylamine compound, such as 2,6-difluoroaniline, in an organic medium containing a relatively acidic alcohol, such as propylene glycol or 2,2,2-trifluoroethanol.
