metal complexes, but strategies to selectively halogenate pyridine C-H precursors are lacking. We designed a set of heterocyclic phosphines that are installed at the 4-position of pyridines as phosphonium salts and then displaced with halide nucleophiles. A broad range of unactivated pyridines can be halogenated, and the method is viable for late-stage halogenation of complex pharmaceuticals. Computational

4-((1H-benzo[d]imidazol-2-yl)oxy)-3-methylpicolinic acid (11) is a key relatedsubstance of Rabeprazole sodium. In this article, this key relatedsubstance is synthesized by using 3-methylpicolinonitrile as a starting material via a five-step processes. By converting 3-methylpicolinonitrile to 4-hydroxy-3-methylpicolinonitrile (13), the preparation of TM becomes practical. This work provides a guarantee
4-((1 H-苯并[ d ]咪唑-2-基)氧基)-3-甲基吡啶甲酸(11)是雷贝拉唑钠的关键相关物质。在本文中,该关键相关物质是使用3-甲基吡啶啉作为起始原料通过五步法合成的。通过将3-甲基吡啶甲基腈转化为4-羟基-3-甲基吡啶甲基腈(13),TM的制备变得可行。这项工作为建立雷贝拉唑钠的质量标准提供了保证。
