Abstract

p - Aminobenzene - sulphonamide and its nuclear substitution products are converted into their water-soluble methylene-sulphonates by treatment with alkali-metal formaldehydebisulphite or its components. The products possess therapeutic properties. Examples are given of the treatment of p-aminobenzene-sulphonamide itself, 3-methoxy-4-aminobenzenesulphonamide and 3-chlor-4-aminobenzene-sulphonamide. Sulphonamides.--3-Methoxy-4-aminobenzenesulphonamide is prepared by condensing acetyl-o-anisidine with chlorsulphonic acid, reacting with ammonia and eliminating the acetyl group from the resulting 3-methoxy-4-acetylaminobenzene-sulphonamide by heating with dilute sulphuric acid. 3-Chlor-4-aminobenzenesulphonamide is similarly prepared from acetyl-o-chloraniline.
