制备方法与用途

制备方法

1. 胺解：在具有搅拌和冷却装置的密闭反应釜中依次加入100质量份的3-氟-4-溴-苯甲酰氯及400质量份二氯甲烷。在搅拌下，缓慢加入41-55质量份的二甲基羟胺盐酸盐，并保持温度在18-24℃之间，反应16-18小时后结束反应，得到反应液。

2. 萃取与浓缩：向上述反应液中加入280-300质量份无离子水进行萃取。分离油层并采用真空浓缩方法，最终得到固体3-氟-4-溴-N-甲氧基-N-甲基苯胺。

3. 亲核取代：将步骤2所得的3-氟-4-溴-N-甲氧基-N-甲基苯胺加入到带有搅拌和冷却装置的密闭反应釜中，再加入400-450质量份四氢呋喃。待温度降至0-5℃后，分批滴加220-240质量份3mol/L的甲基氯化镁溶液，并在滴加过程中控制反应釜内温度不高于24℃。滴加完毕后，在相同温度条件下继续反应2.5-3.5小时，然后结束反应。

4. 分离与纯化：向步骤3所得的反应液中加入180-220质量份无离子水进行萃取操作，分离油层。再用280-310质量份乙酸乙酯和260-280质量份无离子水对有机相进行第二次萃取。最终通过真空浓缩得到固体3-氟-4-溴-苯乙酮。
