制备方法与用途

简介

吡啶是一种具有芳香性的含氮化合物。尽管在自然界中较为罕见，工业用的吡啶通常是通过缩合环合成反应制得，因此原料成本较高。2-羟基砒啶-4-羧酸甲酯是其中一种衍生物，由(R)-2-硫代四氢噻唑-4-羧酸与甲醇及二氯亚硫酰反应生成，产率为98%，主要用作医药中间体。

用途

2-羟基砒啶-4-羧酸甲酯主要用于制药行业作为合成其他药物的中间体。

制备方法

制备2-羟基砒啶-4-羧酸甲酯的过程如下：取10g间硝基苯甲醛（0.066mol）、11g酰乙酸氯乙酯（0.067mol），溶解于60ml苯中，加入1ml哌啶和1ml冰醋酸。在水浴上加热，并使用Dean-Stark分水器不断除去反应生成的水分，回流3小时后将苯蒸出，剩余物加20ml乙醚，冷冻析晶，抽滤干燥得到产品2-羟基砒啶-4-羧酸甲酯16.2g，收率为82%，熔点为92-96℃。
