以3-(苄氧基)异恶唑-5-甲酸甲酯为原料合成(3-(苄氧基)异恶唑-5-基)甲醇的一般步骤:向3-(苄氧基)异恶唑-5-甲酸甲酯(2.33 g,9.99 mmol,1.00当量)的甲醇(50 mL)溶液中分批加入硼氢化钠(756 mg,19.98 mmol,2.00当量)。将反应混合物在15℃下搅拌3小时。通过薄层色谱(TLC,展开剂比例为石油醚:乙酸乙酯=5:1)监测反应进程,确认反应完成。将反应混合物缓慢倒入0.2 M盐酸溶液(200 mL)中,并用乙酸乙酯(150 mL×2)进行萃取。合并有机相,用饱和食盐水(200 mL×2)洗涤,无水硫酸钠干燥,过滤后减压浓缩,得到(3-(苄氧基)异恶唑-5-基)甲醇(1.85 g,9.02 mmol,收率90%),为无色油状物。LC-MS(ESI)m/z:206.1 [M+H]+。
