SUBSTITUTED 1-SULFONYLBENZIMIDAZOLES

摘要

Sulphonylbenzimidazoles of the formula I in which R1, R2 and R3 have the meaning given in Patent Claim 1, are obtained by reaction of a corresponding tautomeric benzimidazole (i.e. a compound I which contains an H atom which can be located on the N atom 3, instead of the SO2R1 group) with a sulphonyl chloride R1SO2Cl. Resulting isomers can be separated. The compounds I are very useful as medicaments for the control of viruses.
