Abstract
Process for the preparation of new benzenesulfonamide derivatives of the general formula i, ** (see formula) ** In which R1 means an alkyl group with 1-carbon atoms, an alkenyl group with 3-4 carbon atoms or a cycloalkyl group with 5-7 carbon atoms, R2 means hydrogen, the methyl or ethyl group, and X means hydrogen, a halogen atom up to the atomic number 35, the methyl, methoxy or methylthio group or the acetyl group, And their addition salts are inorganic or organic acids, characterized in that a compound of the general formula ii, ** (see formula) ** In which X, r1 and r2 have the significance indicated under formula i and R3 means hydrogen, an arylmethyl, diarylmethyl or a triarylmethyl group, the methyl or allyl group, It is condensed with a cyanic acid derivative suitable for reaction, under ring closure, optionally under splitting of an r3-halide and the compound obtained is optionally converted with an inorganic or organic acid into an addition salt.
