Versuchsvorschrift
In the manner of Example II, 7.9 g of 1,1-dimethyl-3-(4-cyano-3-(methylthio)-5-isothiazolyl)urea was oxidized with 3.7 ml of 30% hydrogen peroxide to give 7.0 g of 1,1-dimethyl-3-(4-cyano-3-(methylsulfinyl)-5-isothiazolyl)urea, m.p. 178°-179°. The nmr spectrum was consistent with the assigned structure.
