AbstractThis paper describes a practical approach to the preparation of 4-(2-hydroxyethyl)indolin-2-one, a key intermediate in the synthesis of dopaminergic agonists such as ropinirole—a drug used in the treatment of Parkinson’s disease and restless legs syndrome—and of two sets of protein kinase inhibitors. The sequence starts from commercially available 2-(2-methyl-3-nitrophenyl)acetic acid, which
摘要本文介绍了一种实用的制备方法,用于制备4-(2-羟乙基)吲哚啉-2-酮,它是合成多巴胺能激动剂(例如罗匹尼罗)的关键中间体,罗匹尼罗是用于治疗帕金森氏病和腿不安综合症的药物,和两组蛋白激酶抑制剂。该序列从可商购的2-(2-甲基-3-硝基苯基)乙酸开始,将其分五步转化为所需的目标化合物。鉴于其温和的反应条件,易于实施以及其总收率(59%),该方法为现有方法提供了一种方便的替代途径。 图形概要
