摘要
A novel synthesis of 2-amino-5-methanesulfonylaminobenzenesulfonamide is described. This preparation begins with readily available 4-nitroaniline and proceeds through five steps (isolations) in 41% overall yield. The described chemistry is conducted on a 50- to 100-g scale and does not require extractive workup procedures or chromatographic purifications.
