N-(2,2,2-Trichloro-1-hydroxyethyl)- and N-(2,2-dichloro-1-hydroxy-2-phenylethyl)arenesulfonamides are oxidized with chromium(VI) oxide to give, respectively, N-(arylsulfonyl)trichloroacetamides and N-(aryl sulfonyl)dichloro(phenyl)acetamides. Under analogous conditions N-(2,2,2-trichloro-1-hydroxyethyl)trifluoromethanesulfonamide is converted into 1,1,1-trichloro-2,2-bis(trifluoromethylsulfonylamino)ethane.

The synthesis of 5-bromo-thiophene-2-sulfonic acid 2,4-dichlorobenzoylamide sodium salt on multikilogram scale is described. The initial clinical supplies were made using carbonyl diimidazole to converge the two fragments. A more efficient acid chloride process has been developed, which also provides better control of impurities and color throughout the synthesis.
