During drug synthesis, control of impurities is very important to get high-qualified drugs. A number of studies have devoted to synthesize the impurities and study the structures to support the method of purification. In this paper, we first synthesize one impurity in esomeprazole, rel-2-[[(3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-6-methoxy-1H-benzimidazole, with readily available raw materials, simple
在药物合成过程中,控制杂质对获得高质量药物非常重要。大量研究致力于合成杂质并研究结构以支持纯化方法。在本文中,我们首先合成了埃索美拉唑中的一种杂质,rel-2-[[[((3,5-二甲基-2-吡啶基)甲基]亚磺酰基] -6-甲氧基-1 H-苯并咪唑,原料容易获得,简单易行。操作程序和反应比较温和。此外,我们通过MS,IR,1 H-NMR和HPLC分析表征了其结构。目标化合物的纯度高达99.58%,可作为埃索美拉唑杂质的参考物质。
