Abstract
Process for the preparation of new sulfanilamide derivatives corresponding to the general formula I ** (See formula) ** where R1 and R2 signify, independently of one another, hydrogen, an alkyl, alkoxy or lower alkylthio radical, the cyclopropyl radical or a halogen atom and R3 means hydrogen or the cyclopropyl radical, wherein only one of the radicals R1, R2 or R3 is a cyclopropyl radical, characterized in that a compound of the general formula II is reacted ** (See formula) ** with a compound of formula III ** (See formula) ** where X means the amine group or a nitrogenous group convertible into amine group, one of the two symbols A1 and A2 means the amine group -NH- and the other means the direct bond, Z and X together represent dissociable reactive radicals and R1, R2 and R3 have the meaning set forth above, optionally in the presence of an acid-accepting agent, to form a compound of the general formula IV ** (See formula) ** where R1, R2, R3 and X have the meaning set forth above, convert, if necessary, the group X of the product of the reaction into free amine group and/or react, if desired, a product of the reaction containing as radical R1 and/or R2 a halogen atom (in particular a chlorine atom), with a metal compound of a lower alkanol or alkanol or reduced to remove the halogen atom, or the halogen atoms, R1 and/or R2.
