| titleOfInvention | METHOD OF OBTAINING SULPHONAMIDES |
| abstract | A process for the preparation of sulfonamides of the formula I, where the substituents have the meanings indicated in the description, by the reaction of chlorides of m-nitrobenzoic acid of the formula II with aminosulfones of the formula III in the presence of B equivalents of the base of the formula IV, which is characterized in that in step a) the aminosulfones of the formula III react with B1 equivalents of the base formula IV, and in step b) the reaction mixture obtained in step a) is reacted with m-nitrobenzoic acid chlorides of formula II and B2 with equivalents of a base of formula IV, where B, B1 and B2 have the meanings indicated in the description. |
