制备方法与用途

简介

3-溴-4-氟苯酚在常温常压下呈现黄绿色针状固体，是一种具有特定酸性的苯酚衍生物，并带有独特的酚气味。这种化合物是生产某些树脂、杀菌剂、防腐剂以及药物分子的重要原料。

用途

3-溴-4-氟苯酚常作为药物分子和生物活性物质的合成中间体，在杀菌剂和防腐剂的制备中有着广泛的应用。在合成过程中，主要围绕其结构中的溴单元进行操作；溴原子可以通过Suzuki偶联反应连接上芳基或烷基等。此外，酚羟基可以在碱性条件下进行烷基化反应，生成醚类化合物。

合成方法

在0°C的冰水浴下，将24.4克（80毫摩尔）二甲基叔丁基硅烷保护的3-溴-4-氟苯酚溶解于160毫升四氢呋喃中，然后加入80毫升四丁基氟化铵的四氢呋喃溶液（80毫摩尔）。将混合物搅拌0.5小时后，浓缩以除去四氢呋喃溶剂和未反应完全的四丁基氟化铵。将混合物用乙酸乙酯/正己烷(1:1)稀释，并依次用水和盐水洗涤。分离有机层并用无水硫酸钠干燥，过滤去除固体无水硫酸钠。浓缩后的粗产物溶解在正己烷中（若不溶可以加热使之溶解），通过柱层析（使用0至50%乙酸乙酯/己烷的梯度洗脱）纯化残余物，最终获得淡黄色油状的目标产物12.5克（65.4毫摩尔，产率为82%）。

  摘要：

  作为默克公司正在进行的 NS5A 抑制工作的一部分，我们现在描述我们在 MK-8742 的四环吲哚核心周围引入取代的努力。核心上的氟取代与脯氨酸环上的氟取代相结合，显着提高了针对 GT1a Y93H 的效力。然而，GT2b 效力没有得到改善。将氟取代限制在四环吲哚核心的 C-1 对抵抗相关变体（例如 GT1a Y93H 和 GT2b）的效力以及 PK 曲线具有积极影响。鉴定了在野生型 GT1a 到 GT2b、GT1a Y93H 和 GT1a L31V 之间效力降低的化合物，例如 62。
