制备方法与用途

应用

5-溴-1-甲基苯并咪唑可用作有机合成中间体和医药中间体，主要用于实验室研发过程和化工生产过程中。

制备

在26 mmol化合物5-溴-2-(甲基氨基)苯胺和50 mL二甲苯的混合物中加入7.7 mmol原甲酸三乙酯。所得悬浊液加热回流7小时后冷却，抽滤得到固体，再溶于90 mL二氯甲烷中。该溶液依次用50 mL 10%碳酸钾和50 mL饱和食盐水各洗涤一次，然后使用无水硫酸镁干燥。减压蒸出溶剂后，将剩余的液体浓缩至干，并再次溶于二氯甲烷中，采用相同的方法进行洗涤和干燥以回收有机物。合并后的有机物通过硅胶柱层析，洗脱剂为石油醚/乙酸乙酯（3∶1），最终得到5-溴-1-甲基苯并咪唑6.5 g，收率为87%。
