制备方法与用途

用途

2-溴-3-羟基-4-甲氧基苯甲醛主要用于有机合成及化工医药研发过程中。

制备

2-溴-3-羟基-4-甲氧基苯甲醛可通过异香草醛为原料，通过溴代反应制备得到。

将20.01g（132.00mmol）的异香草醛溶于120.4mL冰醋酸中，加入0.68g铁粉和21.59g无水乙酸钠。逐滴加入7.04mL液溴的冰醋酸溶液（总量为50mL），控制反应温度在23-25℃之间，滴加完毕后，继续保持此温度范围，反应3小时。通过TLC监测反应进程，直至反应完全。

将反应混合物倒入冰水中，搅拌30分钟后过滤，用水洗涤至无冰醋酸味，得到粗产物。再用乙酸乙酯和石油醚重结晶，并在真空条件下干燥，最终获得目标产物（24.59g，产率81.13%）。
