制备方法与用途

简介

2-氯-3-氟-5-溴吡啶在常温常压下为白色或灰白色固体，广泛应用于农药、助染剂以及药品、消毒剂和染料等产品的合成原料。

用途

2-氯-3-氟-5-溴吡啶可用作多种化合物的合成原料。由于其缺电子的特性及卤素原子（氯和溴）的易离去性质，该物质在芳香亲核取代反应中表现出较高的活性。这使得它能够与亲核试剂发生反应，进一步应用于药物、消毒剂、染料和农药等领域。

制备方法

将5-溴-3-氟-2-羟基吡啶 (10.0 g) 悬浮于磷酰氯 (50 mL) 中，在 150 °C 下加热 4 小时。随后，将混合物倒入冰水中，并通过添加碳酸钾调节 pH 至 10。之后用二氯甲烷萃取有机相，再用无水硫酸镁干燥，过滤并真空浓缩，即可得到目标产物。
