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 (S(N)Ar) 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.
将讨论使用微波辅助亲核芳香取代(S(N)Ar)反应合成4-氯-N-(萘-1-基甲基)-5-(3-(哌嗪-1-基)苯氧基)噻吩-2-磺酰胺(B-355252)。在碳酸铯存在下于二甲基甲酰胺中或在磷酸三钾存在下于N-甲基-2-吡咯烷酮中,利用该方法能够以94%的产率快速生成B-355252的杂芳基醚核心结构。使用NS-1细胞确定了B-355252增强神经生长因子刺激神经突生长能力的评估。
