Abstract

Process for the preparation of new N'-substituted N-arylsulfonylureas, of the general formula I ** (See formula) ** in which m and n are 0, 1, 2 or 3 and, together, 1, 2, 3, 4 or 5; R1 means a lower alkyl group; R2 means a lower alkyl group; R3 means hydrogen or a lower alkyl group; O well R3 and R3 together, in the case that m is 0 and n is 2, they mean an ethylene group, as well as its salts with inorganic or organic bases, characterized in that an isocyanate derivative of the general formula II is reacted ** (See formula) ** in which R1 has the meaning set forth in formula I, with a compound of general formula III ** (See formula) ** in which m, n, R2 and R3 have the meaning set forth in formula I, or with an alkaline or alkaline earth derivative of such a compound, optionally in the presence of a condensing agent and preferably in an inert solvent, and by transforming, if desired, the product of the reaction into a salt with an inorganic base or organic (Machine-translation by Google Translate, not legally binding)
