A procedure for the synthesis of 5-(arylsulfanyl)-2,3-dihydro-6- sulfonamido-3-benzofuranones (1) via 5-bromo-3-methoxy-6-nitrobenzofuran (4) as a common advanced synthetic intermediate has been developed. The key step consists of a regioselective nucleophilic aromatic substitution of the bromine atom of 4 by an aryl or heteroarylthiol.
