We tried to establish a method for the synthesis of 5-arylthieno[2,3-d]pyrimidin-4-amine analogues via three-step reactions and examined the changes in the solvent, time, and temperature. A novel condition has been developed for the preparation of substituted 2-aminothiophenes employing the Knoevenagel condensation followed by the Gewald method and in the last step to form thieno[2,3-d]pyrimidines by using formamidine acetate. All the synthesized 5-arylthieno[2,3-d]pyrimidin-4-amines are unknown and were characterized by IR, 1H-NMR, 13C-NMR, and CHN analysis.

2-氨基-4-芳基噻吩-3-甲腈和乙酸甲脒作为合成5-芳基噻吩并[2,3-d]嘧啶-4-胺的关键结构单元

我们试图建立一种通过三步反应合成5-芳基噻吩并[2,3- d ]嘧啶-4-胺类似物的方法,并考察了溶剂、时间和温度的变化。开发了一种新的条件,用于制备取代的 2-氨基噻吩,采用 Knoevenagel 缩合,然后采用 Gewald 方法,最后一步使用乙酸甲脒形成噻吩并[2,3- d ]嘧啶。所有合成的5-芳基噻吩并[2,3- d ]嘧啶-4-胺都是未知的,并通过IR、1 H-NMR、13 C-NMR和CHN分析进行了表征。
