Abstract
Sulphonamides of the general formula <FORM:0595235/IV/1> or <FORM:0595235/IV/2> in which X is a chlorine or bromine atom or an amino or acylamino group are prepared by heating the sulphonamide <FORM:0595235/IV/3> with a guanidine salt in the presence of a strong base at a temperature such that ammonia is formed. In a modification, the guanidine salt is reacted with the alkali metal derivative of the sulphonamide. The process may be effected at 110 DEG to 200 DEG C., if desired in the presence of a solvent such as ethylene glycol. Guanidine sulphate and carbonate are specified as suitable guanidine salts. In an example, sulphanilamide, guanidine sulphate, potassium hydroxide and ethylene glycol are heated to 160 DEG C. for 45 minutes, and p-aminobenzene-sulphonyl guanidine is separated from the product.
