摘 要
本文简述了外周 T 细胞淋巴瘤(PTCL)及其发病机理和治疗药物的研究进展,介绍了治疗外周 T 细胞淋巴瘤药物Belinostat的作用机制、药效动力学、临床研究以及贝利司他关键中间体合成工艺概况。
N-苯基-3-丙烯酸甲酯苯磺酰胺是合成Belinostat的关键中间体,本文经理论分析和实践,对其合成工艺进行了探索和改进,探讨了反应温度、反应时间、催化剂、溶剂等条件对产率的影响,得到了一条较合理的合成工艺路线。即以间羧基苯磺酸钠为起始原料进行酯化反应,经SOCl2氯化,苯胺酰化,再在氢化铝锂的条件下经还原得到3-(羟甲基) -N-苯基苯磺酰胺,接着采用硅胶负载的沙瑞特试剂为氧化剂,将羟甲基氧化,之后与磷酰基乙酸三甲酯经Horner-Wadsworth-Emmons 成烯化反应缩合得到(2E)-3-[3-(苯胺磺酰基)苯基]-2-丙烯酸甲酯,再通过水解酸化生成( 2E) -3-[3-(苯胺磺酰基) 苯基]-2-丙烯酸甲酯。
本论文的改进和创新之处在于:
1、将3-(甲氧基羰基)苯磺酰氯的制备中的三氯氧磷换成二氯亚砜,二氯亚砜溶解性较好,操作简便,节省实验时间。
2、将3-(羟甲基)-N-苯基苯磺酰胺的制备中的无水氯化锂换成氢化铝锂,氢化铝锂还原性强,不需加热,室温下反应,反应时间短
3、将N-苯基-3-烯丙酸甲酯苯磺酰胺的制备中的氢化钠换成无水碳酸钠,无水碳酸钠比.、氢化钠安全可靠,稳定性较强,实验操作简单,价格便宜。

The synthesis of Belinostat key intermediate
Abstract
This paper summarizes the research progress of peripheral T-cell lymphoma (PTCL) and its pathogenesis and therapeutic drug, and describes the mechanism of action, pharmacodynamics, clinical research and the key to the treatment of peripheral T-cell lymphoma drug Belinostat Synthesis of intermediates.
Based on the theoretical analysis and practical attempt, this paper chooses to design a reasonable synthetic route of Belinostat key intermediates, and explores the feasibility of the route, and examines some reaction conditions of the process improvement section. That is, the starting material is esterified with sodium carboxybenzene sulfonate, followed by chlorination with thionyl chloride, followed by acylation with aniline to give methyl 3- (anilino) benzoate, (Hydroxymethyl) -N-phenylbenzenesulfonamide was added under conditions of lithium aluminum hydride followed by the oxidation of the compound with a silica gel-loaded sarrett reagent as an oxidizing agent, and the compound was reacted with trimethyl phosphoryl (2E) -3- [3- (phenylaminosulfonyl) phenyl]-2-propenoate was obtained by condensation of Horner-Wadsworth-Emmons, followed by hydrolysis to give (2E) -3- [3- ( Aniline sulfonyl) phenyl]-2-propenoate.
The improvement and innovation of this thesis lies in:
1. The preparation of 3- (methoxycarbonyl) benzenesulfonyl chloride in the preparation of phosphorus oxychloride phosphorus dioxide, dichlorosulfone solubility is good, easy to operate, save the experiment time.
2. The anhydrous lithium chloride in the preparation of 3- (hydroxymethyl) -N-phenylbenzenesulfonamide was replaced by lithium aluminum hydride, and the lithium aluminum hydride was highly reducible without heating, reaction at room temperature, short reaction time
3. N-phenyl-3-allyl methyl ester benzenesulfonamide in the preparation of sodium hydride in anhydrous sodium carbonate, anhydrous sodium carbonate than sodium hydride safe and reliable, strong stability, experimental operation is simple and inexpensive.
