The reaction of 1,3,5-triazine and 2,4,6-tri(trifluoromethyl)-1,3,5-triazine with in situ generated 1-substituted 5-amino-1H-imidazoles led to a set of functionalized purines. The developed practical route could serve as a fundament for the preparation of related ADA inhibitors.
1,3,5-三嗪和2,4,6-三(三氟甲基)-1,3,5-三嗪与原位生成的1-取代的5-氨基-1 H-咪唑的反应导致一组官能化嘌呤。所开发的实用途径可作为制备相关ADA抑制剂的基础。
