摘要

A process for the preparation of pyrazoyl-sulfanilamide compounds with antipyretic, anti-inflammatory and bacteriostatic activities, represented by the formula: ** (see formula) ** Where r is an alkyl radical, r'is an aryl radical and r "is a heterocyclic radical with or without substituents, which process is characterized by reacting an aldehyde of the general formula ** (see formula) ** Where r is an alkyl radical and r'is an aryl radical, with an aqueous solution of sodium bisulfite or metabisulfite and a sulfonamide of the general formula ** (see formula) ** Where r "is a heterocyclic radical, and subjecting the solution to evaporation to dryness under vacuum.
