Abstract

Procedure for the preparation of benzenesulfonylureas of the formula **(See formula)** wherein: R signifies lower alcohol, lower alkoxy, halogen, -NH2, trifluoromethyl, acetyl, or the acylaminoalcohyl group, where acyl means the radical of an aliphatic, cycloaliphatic, aromatic or heterocyclic carboxylic acid, or the radical of an acid carbamic and the alcohol group has 1 to 4 carbon atoms; R1 signifies lower alcohol, cycloalkyl, cycloalkoxy, and cycloalkenyl, which may be substituted with a lower alcohol or lower alkoxy group, or a polycyclic radical, which may be linked to the nitrogen atom through a lower alcohol group; R2 signifies hydrogen or together with R1 and the contiguous N atom signifies a 5-7 membered ring which is eventually substituted with a lower alcohol group or an endoalkylene group, and its salts, characterized in that they are cleaved with organic bases benzenesulfonylisoureaethers of the formula **(See formula)** where R, R1 and R2 have the above meanings and represents 1 to 3 carbon atom alcohol, and the reaction products are isolated either in the form of salts or in the form of free acids.
