4]thiadiazol-5-ylmethoxy)phenoxy)propionic acid sodium salt (17) is described and compared with earlier in-house preparations of this important target compound. Key concerns around a large-scale synthesis of this thiadiazole derivative were a large number of purification steps, the use of dichlorobenzene as a solvent, and a possible large-scale Baeyer–Villiger oxidation. This paper describes a straightforward preparation
PPARα,δ激动剂2-甲基-2-(2-甲基-4-(3-(4-(三氟甲基)苯基)[1,2,4]噻二唑-5-基甲氧基)苯氧基)丙酸钠的制备描述了该盐(17)并将其与该重要目标化合物的内部更早制备方法进行了比较。大规模合成该噻二唑衍生物的关键问题是大量的纯化步骤,使用二氯苯作为溶剂以及可能的大规模拜尔-维利格氧化。本文介绍了使用甲基氢醌(MHQ)作为廉价的前体直接制备目标激动剂的方法,该方法无需进行氧化步骤。
