the preparation of 2-aryl-8-fluorobenzyl-1,2,4-triazolo[5,1-i]purines 2, starting from 2-aryl-7,8-diamino-1,2,4-triazolo[1,5-c]pyrimidines 9. Our synthetic procedure represents the first example of a feasible approach for the synthesis of 2,8-disubstituted triazolo[5,1-i]purines. New syntheses of 5-amino-3-arylpyrimido[5,4-e]1,2,4-triazines 12 and 8-fluorobenzyl-6-hydrazinopurines 15 are also reported
本文介绍了从2-芳基-7,8-二氨基-1,2,4-三唑基开始制备2-芳基-8-氟苄基-1,2,4-三唑并[5,1- i ]嘌呤2的方法。 [1,5- c ]嘧啶9。我们的合成方法代表了合成2,8-二取代的三唑并[5,1- i ]嘌呤的可行方法的第一个实例。还报道了5-氨基-3-芳基嘧啶[5,4- e ] 1,2,4-三嗪12和8-氟苄基-6-肼基嘌呤15的新合成。
