Acedapsone (

Acedapsone is the INN for diacetyldapsone. It was synthesized and developed in 1937 by Ernest Fourneau and his team in the pharmaceutical chemistry laboratory of Pasteur Institute,^[1] and it was marketed as Rodilone by the Rhône-Poulenc company.^[2]

It is a long-acting prodrug of dapsone. It is used for treating leprosy.^[3]

It crystallises as pale yellow needles from diethyl ether, and as leaflets from dilute ethanol. It is slightly soluble in water.^{[citation needed]}

Synthesis

Acedapsone is conveniently prepared by acetylation of dapsone.
