by sequential treatment with ethanolic ammonia and secondary amines. These compounds were successfully reacted with various isothiocyanates in the presence of sodamide in DMF to form the new thiazolo[4,5-d] pyrimidine derivatives.
通过用乙醇氨和仲胺顺序处理,可以从新制备的5-溴-2,4-二氯-6-甲基嘧啶中容易地获得4-氨基-5-溴-2-取代的氨基嘧啶。这些化合物成功地与各种异硫氰酸酯在DMF中的磺酰胺存在下反应,形成新的噻唑并[4,5- d ]嘧啶衍生物。
