An improved process for the preparation of N-([1,2,4]triazolopyrimidin-2-yl)aryl sulfonamides |
| 摘要 |
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. |
