| titleOfInvention | PROCEDURE FOR THE PREPARATION OF NEW SULFONAMIDES. |
| abstract | Process for the preparation of new sulfonamides of the general formula I, in which R represents an aromatic or heterocyclic radical, which may be optionally substituted, and Y represents a halogen- and/or alkoxy-substituted pyrazinyl or pyridazinyl radical, with the condition that if R represents an unsubstituted phenyl radical, Y cannot represent an alkoxy-substituted pyridazinyl radical, and salts thereof, comprising: a) reacting an aldehyde of general formula IV, in which R has the same meaning as indicated above, with a compound of the general formula V, in which Y has the same meaning as indicated above; or b) reacting an aldehyde of the general formula IV with p-aminobenzene sulfonamide and reacting the compound thus obtained with a compound of the general formula VI, in which Y has the same meaning as indicated above and A is a reactive group or atom; or c) reacting an aldehyde with a sulfonamide and reacting the compound thus obtained with an aldehyde of the general formula IV, and if desired, converting a compound of the formula I thus obtained into a salt thereof, or releasing a compound of the general formula I from its salt.
