制备方法与用途

用途

1,5-二氮萘是一种医药中间体，可通过4-氨基吡啶作为起始物料制备得到，并用于制备CXCR4抑制剂。

制备

将浓硫酸（30 mL）缓慢加入20 mL水中，依次加入D22-1（3.76 g, 40.0 mmol）、甘油（12.52 g, 136 mmol）和间硝基苯磺酸钠（19.8 g, 88.0 mmol），加热至130℃，搅拌过夜。随后加入2 N氢氧化钠水溶液调节pH值至10，过滤后用二氯甲烷（2 × 200 mL）萃取两次，合并有机相并减压浓缩。通过硅胶柱层析纯化（石油醚：乙酸乙酯 = 20:1 至 1:1），最终得到黄色固体中间体D22-2即1,5-二氮萘（900 mg，收率69%）。
