| titleOfInvention | Process for the preparation of sulfonamides |
| abstract | The present invention relates to a process for the preparation of sulfonamides of formula (II) which comprises reacting an aniline of formula (I) at elevated temperature in the presence of a catalytic amount of (i) a B-1 amide or (ii) a high boiling tertiary amine B-2. R1-SO2-Z is reacted with a sulfonating agent of the formula I, wherein X and Y in the general formulas (I) and (II) and Z are independently hydrogen, halogen, alkyl, haloalkyl, amino, nitro, alkoxy, hydroxy, anhydridyl, alkylthio, arylthio, aryloxy, alkylsulfonyl, arylsulfonyl and optionally substituted aryl, wherein the substituents are selected from one or more atoms and / or groups : halogen, C 1-20 alkyl, C 1-20 alkoxy, nitro, amino, amido, alkylthio, aryl, arylthio, aryloxy, alkylsulfonyl and / or aryl. sulfonyl; R in the formulas (I) and (II) is a hydrogen atom, an alkyl group, a haloalkyl group, an aryloxy group, an optionally substituted aryl group and an optionally substituted heterocyclic group, wherein the substituents are selected from one or more atoms and / or or are halogen, C 1-20 alkyl, C 1-20 alkoxy, nitro, amino, amido, alkylthio, aryl, arylthio, aryloxy, alkylsulfonyl and / or arylsulfonyl and R1 is hydrogen, alkyl, haloalkyl or aryl.
