Reactions of sulfonamides RSO2NHR' with chlorodifluoromethane and solid alkali give the corresponding derivatives RSO2N(CHF2)R' containing a difluoromethyl group on the nitrogen atom. Sulfonamides derived from 2-aminobenzothiazole and 2- and 4-aminopyridines react with chlorodifluoromethane at the endocyclic nitrogen atom.
