制备方法与用途

概述

3-溴-2-甲基苯甲醛可用作医药合成中间体。它可以通过从起始原料3-溴-2-甲基苯甲酸还原得到(3-溴-2-甲基苯基)甲醇，再通过氧化制备得到。

制备

步骤1： 将硼氢化钠（0.630克，16.7毫摩尔）悬浮在四氢呋喃（82毫升）中，并添加3-溴-2-甲基苯甲酸（3.00克，14.0毫摩尔）。搅拌混合物直至气体逸出停止后，分小份加入碘（1.77克，6.98毫摩尔）。在室温下继续搅拌2小时，然后通过缓慢添加2N盐酸溶液小心淬灭反应。用水稀释所得混合物，并用醚萃取。将有机层分别用2N NaOH水溶液洗涤三次，再用盐水洗涤一次，经硫酸镁干燥、过滤并浓缩，最终得到白色固体(3-溴-2-甲基苯基)甲醇（2.79克）。

步骤2： 在氮气保护下，将二氯甲烷（55毫升）中二甲亚砜（2.99毫升，41.8毫摩尔）的溶液冷却至-78℃。缓慢滴加草酰氯（20%于二氯甲烷中的溶液，10.4毫升，20.8毫摩尔）。在-78℃下搅拌30分钟后，通过套管逐滴滴加(3-溴-2-甲基苯基)甲醇（2.79克，13.9毫摩尔）的二氯甲烷溶液（15毫升）。继续搅拌1小时后，缓慢滴加三乙胺（5.8毫升，41.8毫摩尔），并逐渐升温至室温。混合物用饱和碳酸氢钠水溶液、水和盐水洗涤。将有机层经硫酸镁干燥、过滤并浓缩，最终得到3-溴-2-甲基苯甲醛（2.76克）。
