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.
通过选择3-哌啶或3,5-二甲基吡啶作为碱,改进了N-芳基磺酰氯与N-([1,2,4]三唑吡咯-2-基)胺催化偶联反应,形成N-([1,2,4]三唑并[2,3-d] 嘧啶-2-基)芳基磺酰胺。
