Synthesis of Lesinurad via a Multicomponent Reaction with Isocyanides and Disulfides
摘要:
An efficient synthesis of Lesinurad, a selective uric acid reabsorption (URAT1) inhibitor, is described in this article. The route to synthesis of Lesinurad avoids the use of thiophosgene and the formation of thiols. The key reaction in this synthesis is construction of the 1,2,4-triazole ring in 72% yield. The title product is obtained in 45% yield over 5 steps.
