| titleOfInvention | PROCEDURE FOR THE PREPARATION OF DERIVATIVES OF 4-SULFA-MOIL-META-TOLUIDINA. |
| abstract | Procedure for the preparation of 4-sulfamoyl-meta-toluidine derivatives of the general formula I **(See formula)** in which R1 signifies a phenyl, furyl or thionyl radical, R2 signifies the carboxyl or tetrazolyl group (5) and n signifies numbers 1 and 2, and their pharmacologically compatible salts, characterized in that a) compounds of the general formula are reacted II **(See formula)** in which R3 has the same meaning as R2 or represents a group capable of being transformed into R2, Y means hydrogen or an acyl radical and X means a halogen atom or a nitro group, with amines of the general formula III H2N - (CH2) n - R1 (III), in which R1 and n have the meanings indicated above; or b) compounds of the general formula IV are reacted **(See formula)** in which R3 and Y have the meanings indicated above, with compounds of the general formula V Z - (CH2) n - R1 (V) in which R1 and n have the meanings indicated above and Z constitutes a reactive ester group, or with compounds of the general formula VI OHC - (CH2) m - R1 (VI) wherein R1 has the meanings indicated above and m means the numbers 0 or 1, and optionally hydrogenates in a manner known per se at the same time or thereafter; and in the case in which R3 represents a group capable of being transformed into a carboxyl group or a tetrazolyl radical (5), it becomes, in a manner known per se, into the radical R2 and, if Y represents an acyl radical, it is separated this in a manner known per se, after which the compounds I obtained are transformed, if desired, into their pharmacologically compatible salts.
