- Sulfonyl-benzoylguanidines are known and are described, for example, in EP 0 758 644 A1. These substances are inhibitors of the cellular Na + / H + antiprotector, ie active substances which inhibit the Na + / H + exchange mechanism of the cells (Düsing et al., Med. Klin. 1992, 87, 367- 384) and thus represent good antiarrhythmic agents, which are particularly suitable for the treatment of arrhythmias that occur as a result of a lack of oxygen.
- these compounds can also be used as therapeutic agents in diseases caused by cell proliferation, such as arteriosclerosis, diabetes and late diabetic complications, tumor diseases, fibrotic diseases, in particular of the lungs, liver and kidneys, and organ hypertrophies and hyperplasias.

- the compounds of the formula I can be prepared, for example, according to EP 0 758 644.
- the syntheses known hitherto are based on the introduction of alkylsulfone groups into the ring of a corresponding aromatic carboxylic acid and comprise a large number of individual steps with unsatisfactory yields in some cases.
- the known processes for industrial production have disadvantageous reaction conditions.
- the introduction of alkyl sulfone groups into the ring of an aromatic carboxylic acid by nucleophilic substitution of suitable leaving groups with alkyl sulfanes and subsequent oxidation is problematic because of the extreme and long-lasting odor nuisance caused by alkyl sulfanes, even if these are only released in traces.
