Procedure

A solution of 2-(4'-methylthiophenyl)-4-trifluoromethyl-1,2,4-oxadiazolidine-3,5-dione (29.2 grams; 0.10 mol) in acetone (200 ml) is charged into a glass reaction vessel equipped with a mechanical stirrer. Hydrogen peroxide (16 grams; 0.14 mol) is then slowly added, with stirring, at room temperature. Stirring is continued for a period of about 72 hours after the addition is completed. After this time the solvent is removed from the reaction mixture by evaporation resulting in a solid product. The product is washed, recrystallized, and dried to yield 2-(4'-methylsulfinylphenyl)-4-trifluoromethyl-1,2,4-oxadiazolidine-3,5-dione.
