An improved process for the preparation of n-([1, 2, 4]triazopolyrimidin-2-yl)aryl sulfonamides |
| abstract |
The N-arylsulfilimine-catalyzed coupling of aromatic sulfonyl chlorides with N-([1, 2, 4]triazolopyrimidin-2-yl)amines to form N-([1, 2, 4]triazolo-pyrimidin-2-yl)aryl sulfonamides is improved by the selection of 3-picoline or 3, 5-lutidine as the base. |
