Abstract
4-(Di-n-propylsulfamyl)benzoic acid is an important drug, known under commercial names such as benemid or probenecid [1]. It's preparation under mild conditions by an electrochemical method is described. The method involves cathodic generated oxygen radical-anion which selectively converts the methyl group of 4-(Di-n-propylsulfamyl)toluene to carboxylate. The sulfonamide group which would be reduced under high cathodic potential is not attacked under these conditions. This method circumvents safety problems and the need for corrosive reagents involved in chemical methods of preparation.
