制备方法与用途

化学性质

2-羟基-5-硝基-3-三氟甲基吡啶在常温常压下为固体状，是一种吡啶类衍生物。其结构中2号位的羟基和吡啶环上的双键构成的烯醇式会互变异构化为酰胺结构。

应用

该化合物可作为有机合成中间体和医药中间体，主要用于实验室研发和化工生产过程中。

合成

在-10℃下将24毫升（0.55摩尔）硝酸缓慢滴入含有20.00克（0.12摩尔）2-羟基-3-（三氟甲基）吡啶的硫酸溶液中。随后，在40℃下搅拌反应混合物6小时。通过TLC点板确认反应进程，待反应完成后，将反应混合物加入冰水中，用饱和NaOH水溶液调节pH值至4-5，并用乙酸乙酯萃取水层。得到的有机层经饱和盐水洗涤、无水硫酸钠干燥后过滤并减压浓缩，即可获得2-羟基-5-硝基-3-三氟甲基吡啶。
