ABSTRACT A new route for the preparation of pomalidomide is described in the study. The synthetic procedure starts from 4-nitroisobenzofuran-1,3-dione and 3-aminopiperidine-2,6-dione hydrochloride via a three-step reaction resulting in a total yield of 65% with a high-performance liquid chromatographic (HPLC) purity of 99.56% and a low palladium residue level of 2 ppm. This method can be deemed as
摘要 该研究描述了一种制备泊马度胺的新途径。合成过程从 4-硝基异苯并呋喃-1,3-二酮和 3-氨基哌啶-2,6-二酮盐酸盐开始,经过三步反应,总产率为 65%,具有高效液相色谱 (HPLC) 纯度99.56% 和 2 ppm 的低钯残留水平。该方法是制备泊马度胺的一种高效、实用、环保的合成路线。图形概要
