METHOD FOR PRODUCING FLUORINATED M-NITROBENZOYL CHLORIDES

A process for preparing sulfonamides I where the variables are each as defined in the description, by reacting m-nitrobenzoyl chlorides II with amino sulfones III, under the influence of B equivalents of base IV, wherein, in step a), the amino sulfone III is reacted with B1 equivalents of base IV, a...

Summary:A process for preparing sulfonamides I where the variables are each as defined in the description, by reacting m-nitrobenzoyl chlorides II with amino sulfones III, under the influence of B equivalents of base IV, wherein, in step a), the amino sulfone III is reacted with B1 equivalents of base IV, and, in step b), the reaction mixture resulting from step a) is reacted with m-nitrobenzoyl chlorides II and B2 equivalents of base IV; where B, B1 and B2 are each as defined in the description.
