Synthesis

edit

Dapsone is somewhat inconvenient to administer to patients because of its rather low water solubility.

 
Acediasulfone synthesis:[1] CH 254803  and CH 278482  (1949, 1952, to Cilag Ltd.); Rawlins, U.S. patent 2,589,211 (1952 to Parke-Davis).

In the search for more easily administered drugs, dapsone (1) was reacted with bromoacetic acid to give acediasulfone (2) which can be administered as a water-soluble salt.
