described from 3‐pyridinecarboxaldehyde, thiourea, and ethyl cyanoacetate. Alkylation of 1 with mono‐ and dihaloalkanes under different conditions, provided 2a,b, 3a,b, and 4a‐i. Halogenation of 4g with POCl3 yielded 5 which underwent nucleophilic substitution with amines to give 6a‐g. Fusion of 4a with aromatic and heterocyclic amines at 160°C gave the substitution products 7a‐c. Some of the compounds
5-氰基-6-(3-吡啶基)-2-硫尿嘧啶 (1) 的合成已被描述为由 3-吡啶甲醛、硫脲和氰基乙酸乙酯。1 在不同条件下与单卤代烷烃和二卤代烷烃进行烷基化,得到 2a、b、3a、b 和 4a-i。用 POCl3 卤化 4g 得到 5,其与胺进行亲核取代得到 6a-g。4a 与芳香族和杂环胺在 160°C 融合得到取代产物 7a-c。筛选了一些化合物的抗利什曼原虫活性,但其中只有一种 (6d) 表现出非常显着的活性。
