A novel and facile one-pot procedure for the preparation of 2,4-diamino-6-substituted-s-triazine derivatives (IIa-n) was reported. The scope of its application was demonstrated with a number of examples. The new procedure involved treatment of proguanil or chloroproguanil with acyl chloride or alky chlorooxoacetate in pyridine at ice cold temperature followed by reflux overnight to give good yields
报道了一种新颖且容易的一锅法制备2,4-二氨基-6-取代的-s-三嗪衍生物(IIa-n)。通过大量示例演示了其应用范围。新方法包括在冰冷温度下,用吡啶中的酰氯或烷基氯氧乙酸乙酸酯处理丙胍或氯丙胍,然后回流过夜,得到所需产物的良好收率。
