N-arylsulfilimine compounds, such as S,S-dimethyl-N-(2,6-dichlorophenyl)sulfilimine, were prepared and found to catalyze the re-action of aromatic sulfonyl chloride compounds, such as 2-chlorosulfonyl-7-fluoro-5-ethoxy[1,2,4]-triazolo[1,5-c]pyrimidine, with aromatic amine compounds, such as 2,6-dichloroaniline, to form N-arylarylsulfonamide compounds, such as N-(2,6-dichlorophenyl)-7-fluoro-5-ethoxy-[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide. The aryl moiety of the N-arylsulfilimine catalyst and the aryl moiety of the aromatic amine compound were generally chosen to be identical. |
