3-Phenyl (or meta or para-substituted phenyl)-4-permissibly substituted-5-isothiazolecarboxylic acids, salts, esters and simple amides, used to lower uric acid levels in mammals.

4-Amino-3-arylisothiazole-5-carboxylateesters are converted to the corresponding desamino, chloro, bromo, and iodo esters by processes involving nonaqueousdiazotization. These related procedures open up the possibility for the conversion of readily available heterocyclic ortho-amino esters and nitriles to related heterocyclic derivatives, which are not easily obtained by alternate routes.
