Abstract

Process for the preparation of new sulfanilamide derivatives of the general formula i ** (see formula) ** In which R1 means an alkyl group with not more than 5 carbon atoms, a cycloalkyl or cycloalkenyl group with not more than 7 carbon atoms, and its addition salts with inorganic or organic acids, characterized in that a compound of the general formula ii, ** (see formula) ** In which R1 has the significance indicated under formula i, R2 means hydrogen, an arylmethyl, diarylmethyl or a triaethylmethyl group and X means a radical which can be converted into the free amino group by hydrolysis or reduction, or, if r2 is hydrogen, also means the free amino group, It is reacted and cyclized with a cyanic acid derivative suitable for reaction, if desired the reaction product is hydrolyzed or reduced for transformation of the group x into the free amino group and the compound obtained is optionally converted with an inorganic or organic acid into a addition salt.
