制备方法与用途

应用方面，6-氨基吡啶甲酸甲酯将在核酸、蛋白质、癌变基因、病毒等相关的化学、生物、食品、环境、医学及病理学等领域展现出广阔的前景。

制备方法如下：将10克6-氨基吡啶-2-羧酸溶解于150毫升甲醇中，滴加20毫升浓硫酸，并回流反应16小时。大部分甲醇通过真空除去后，残渣倒入冰水中，用6N氢氧化钠溶液调节pH至8-9，然后使用乙酸乙酯进行萃取。有机相用水洗，再在硫酸钠上干燥、过滤并浓缩，最终得到标题化合物6-氨基吡啶甲酸甲酯，产率为7.5克。

  A new annulation method for the preparation of the imidazo[1,2-a]pyridine ring system under mild conditions is presented. Treatment of a 2-aminopyridine with a dimethylketal tosylate in acetonitrile at elevated temperature (80–140 °C) in the presence of catalytic Sc(OTf)3 provides the imidazo[1,2-a]pyridine product in good yield. The annulation method is broadly applicable to electron-poor 2-aminopyridines

  提出了一种在温和条件下制备咪唑并[1,2- a ]吡啶环体系的新方法。在催化的Sc（OTf）3存在下，在高温（80–140°C）下，在乙腈中用甲苯磺酸二甲基缩酮酯处理2-氨基吡啶，可得到高产率的咪唑并[1,2- a ]吡啶产物。该成环方法广泛适用于电子贫乏的2-氨基吡啶，并通过溴代酮与富电子和中性底物的反应，与经典的咪唑并[1,2- a ]吡啶环体系制备显示出互补性。讨论了过程的范围和机械方面的考虑。
