azathioprine analogs - 2-subsituted derivatives of 7-methyl-6-(l-methyl-4-nitroimidazol-5-ylthio)purines 5 has been achieved by the reaction of 2-subsituted 6-purinethiones 4 with 5-chloro-1-methyl-4-nitroimidazole in ethanol. In the case of 7-methyl-2,6-dithioxanthine 4j, reaction in DMF gave di(imidazolyl) product 51. The key step in this synthesis was preparation of the appropriate 2-substituted 6-purinones
通过 2-取代的 6-嘌呤硫酮 4 与 5 -氯-1-甲基-4-硝基咪唑的乙醇溶液。在 7-甲基-2,6-二硫代黄嘌呤 4j 的情况下,在 DMF 中反应得到二(咪唑基)产物 51。该合成的关键步骤是制备合适的 2-取代的 6-嘌呤酮 2 和 6-氯嘌呤 3,它们进一步转化为 6-嘌呤硫酮 4。
