制备方法与用途

简介

4-溴-2-氟苯乙酸是一种有机中间体，可由4-溴-1-(溴乙基)-2-氟苯为原料先进行氰基取代反应得到2-(4-溴-2-氟苯基)乙腈，然后与氢氧化钠反应，最后通过酸化获得。

用途

4-溴-2-氟苯乙酸是一种羧酸类有机物，主要用作医药中间体。

制备

在氮气保护下，将2-(4-溴-2-氟苯基)乙腈（397克，1.82摩尔）溶于无水甲醇（500毫升）中，并在20℃的温度下搅拌。一次性加入2.5M氢氧化钠溶液（2.22升，5.56摩尔），然后将反应混合物升温至80℃并搅拌5小时。接着，浓缩反应液，并使用浓盐酸调节pH值至5。随后，用乙酸乙酯（1.5升×2）进行萃取。重复上述步骤制备另外两个批次的产物。最后，合并三个批次的有机萃取液，经过饱和食盐水洗涤、硫酸钠干燥、过滤和真空浓缩后，最终得到纯度较高的4-溴-2-氟苯乙酸（1200克，收率92%）。

  腹痛和排便习惯异常是肠易激综合症（IBS）患者治疗不当的主要症状。尽管IBS的病因尚不完全清楚，但胃肠道（GI）的许多功能是由肠神经系统（ENS）调节的。炎症或应激诱导的生长因子或细胞因子的表达可能导致胃肠道内脏传入神经元过度神经支配，并有助于IBS的病理生理。转染（RET）期间重新排列的神经元生长因子受体酪氨酸激酶对ENS的发展至关重要，例如Hirschsprung患者携带RET功能丧失突变且缺乏正常的结肠神经支配导致结肠梗阻。相似地，成人ENS中的RET信号通过促进突触形成，信号传递和神经元可塑性来维持神经元功能。ENS中RET的抑制代表了一种新的神经元功能和IBS患者症状正常化的治疗策略。本文中，我们描述了我们的筛选工作以及随后的结构-活性关系（SAR），以优化该系列的效价，选择性和诱变性，从而发现了首屈一指的肠道限制性RET激酶抑制剂2- （4-（4-乙氧基-6-氧代-1,6-二氢
