制备方法与用途

简介

4-溴苯磺酰胺可用作医药合成中间体及有其他相关化合物的中间体。它主要用于实验室研发过程和化工医药的研发过程中，主要通过将4-溴苯磺酰氯与氨水反应制备得到，也可以通过一步法从对溴苯四氟化硼重氮盐获得。

制备

在氮气保护下，将对溴苯四氟化硼重氮盐（338.5 mg，1.25 mmol）、NaN₃（32.5 mg，0.5 mmol）、PPh₃（157.4 mg，0.6 mmol）、Na₂S₂O₅（190.1 mg，1.0 mmol）和TBAB（241.7 mg，0.75 mmol）以及 MeCN/H₂O = 2/1（1 mL）加入 Schlenk 反应管中。反应在80℃下搅拌12小时后冷却至室温，然后向体系中加入10 mL水进行稀释，并用乙酸乙酯（10 mL×3）萃取。经无水硫酸钠干燥、过滤和浓缩处理后，通过柱层析分离得到白色固体4-溴苯磺酰胺（收率70%）。
