The development of an effective synthetic route of lesinurad (RDEA594)

Abstract

Abstract Background Lesinurad is a novel selective uric acid salt transport protein 1 (URAT1) inhibitor which is approved in the USA for the treatment of gout. However, there are some shortcomings among the reported synthetic routes, such as expensive materials, environmental pollution and poor yield. Results In this study, an efficient, practical and environmentally-friendly synthetic route of lesinurad is reported. The main advantages of this route include inexpensive starting materials, mild conditions and acceptable overall yield (38.8%). Conclusion Generally, this procedure is reasonable, reliable and suitable for industrial production. Graphical abstract The improved synthetic procedure of lesinurad (I).
