Reaction of 9-substituted (methyl or benzyl) 1-aminoadenines 1 with hydrazine afforded 9-substituted 6-hydrazinopurines 2 and 1-substituted 5-ammo-4-(4-amino-1,2,4-triazol-3-yl)imidazole (4). The product ratio of 2 to 4 rose with increasing amounts of methanol used as the solvent. When the same reaction was carried out using 1,9-dimethyladenine instead of 1, compounds 2 and 4 were also obtained with
9-取代的(甲基或苄基)1-氨基ade啶1与肼反应,得到9-取代的6-肼基嘌呤2和1-取代的5-氨基-4-(4-氨基-1,2,4-三唑-3-基咪唑(4)。随着使用的甲醇量的增加,产物比为2至4上升。当相同的反应,使用1,9- dimethyladenine代替进行1,化合物2和4也与获得Ñ 6,9- dimethyladenine。讨论了形成2和4的可能机制。
