讨论了用微波辅助亲核芳取代(SNAr)反应合成4-氯- n-(萘-1-甲基)-5-(3-(哌嗪-1-基)苯氧基)噻吩-2-磺酰胺(B-355252)的方法。利用该方法可以在二甲基甲酰胺中碳酸铯存在或n -甲基-2-吡咯烷酮中磷酸三钾存在的情况下快速生成B-355252杂芳基醚核心结构,收率为94%。利用NS-1细胞测定B-355252增强神经生长因子刺激神经突生长能力的评价。
The synthesis of 4-chloro-N-(naphthalen-1-ylmethyl)-5-(3-(piperazin-1-yl)phenoxy)thiophene-2-sulfonamide (B-355252) using a MW-assisted nucleophilic aromatic substitution (SNAr) reaction will be discussed. Utilization of this method allowed for the rapid generation of B-355252 heteroaryl ether core structure in the presence of cesium carbonate in dimethylformamide or tripotassium phosphate in N-methyl-2-pyrrolidone in 94% yield. Evaluation of B-355252 enhancement of nerve growth factor’s ability to stimulate neurite outgrowths was determined using NS-1 cells.
