Versuchsvorschrift

4-Methylphenylisocyanate (19.0 g.) was added during 10 minutes to a solution of methyl N-[1-amino-1-(methylthio)methylene]carbamate (21.2 g.) in methylene chloride (200 ml.). After 2 hours of stirring, sodium methoxide [obtained by dissolving sodium (3.5 g.) in methanol (30 ml.)] was added at 15°-20° C. The subsequent mixture was stirred at that temperature for 18 hours and the resultant solid collected by filtration and dissolved in water (200 ml.). The solution obtained was acidified with concentrated hydrochloric acid and the solid which formed was collected by filtration, washed well with water and dried to give 3-(4-methylphenyl)-6-methylthiotetrahydro-1,3,5-triazine-2,4-dione (29 g., 81%), m.p. 276°-278° C.
