摘 要:改進(jìn)了唑吡坦關(guān)鍵中間體6-甲基-3-氰甲基-2-(4-甲基苯基)咪唑[1,2-a]吡啶的合成工藝。以5-甲基-2-氨基吡啶、4-甲基苯乙酰溴和溴乙腈為原料,無(wú)需催化劑和添加劑,通過(guò)超聲促進(jìn)的三組分串聯(lián)反應,實(shí)現了6-甲基-3-氰甲基2-(4-甲基苯基)咪唑[1,2-a]吡啶的快速合成,收率84%,目標產(chǎn)物結構經(jīng)1H NMR、13C NMR和高分辨質(zhì)譜表征確證。該方法合成路線(xiàn)短、原料廉價(jià)易得、操作簡(jiǎn)便、安全穩定、收率高。為唑吡坦關(guān)鍵中間體的高效合成提供了新思路。 |
關(guān)鍵詞:唑吡坦;關(guān)鍵中間體;超聲促進(jìn);三組分反應 |

Abstract:The synthesis of key intermediate of Zolpidem was improved. The target product was synthesized using 2-amino-5-methylpyridine, α-bromo-4-methylacetophenone and bromoacetonitrile as starting materials by ultrasound-promoted three-component reaction under catalyst-free, oxidant-free and mild conditions. The yield reached 84% and the product was characterized by NMR and HRMS. This method had the advantage of short synthetic route, cheap raw materials, easy operating, safe, stability and high yield, which provided a new strategy for the synthesis of key intermediate-Zolpidem. |
Key words:Zolpidem; key intermediate; ultrasonic promotion; three-component reaction |
