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 X'means a radical which can be converted by hydrolysis or reduction to the free amino group, is reacted with an ester suitable for the reaction of a hydroxy compound of the general formula iii, Oh - r1 (III) In which R1 is an alkyl group with at most 7 carbon atoms, if necessary the reaction product is hydrolyzed or reduced for the conversion of the group x'to the free amino group and the compound obtained is optionally converted with an inorganic or organic acid into the group. An addition salt. (Machine-translation by Google Translate, not legally binding)
