制备方法与用途

简介

4-溴异噻唑是一种医药中间体，可用于实验室研发过程和化工合成过程中。它可以通过一步溴代异噻唑制备得到，并用于制备Bcr-Abl1激酶抑制剂。

应用

4-溴异噻唑同样作为一种医药中间体，可由异噻唑通过一步溴代获得，适用于制备Bcr-Abl1激酶抑制剂。

制备

在95℃下，将5.0 g（58.82 mmol）的异噻唑溶解于37 mL AcOH中，并在20分钟内滴加12.5 g（78.12 mmol）的Br₂。反应混合物在95℃搅拌6小时后冷却至室温，然后倒入100 mL冰水中。所得混合物用200 mL Et₂O萃取两次。有机相用6 N NaOH洗涤至pH为7〜8，并通过无水Na₂SO₄干燥后过滤。将滤液真空浓缩，再通过蒸馏纯化得到白色固体状的4-溴异噻唑（1.5 g，收率15%）。
