Procedure
This toluene slurry of 3-cyclohexyl-6-methylthio-s-triazine-2,4(1H,3H)-dione sodium salt is then agitated with 650 parts of water for 0.15 hrs. The aqueous layer is separated and reacted at 25°-30° during 0.25 hrs with 57 parts of dimethyl sulfate. After the dimethyl sulfate is added, the pH of the reaction is maintained at pH 9-9.5 by addition of a total of 7.5 parts of 50% aqueous sodium hydroxide. The total reaction time is 1.8 hrs at which time filtration and drying gives 70 parts of white 1-methyl-3-cyclohexyl-6-methylthio-s-triazine-2,4(1H,3H)-dione, m.p. 137°-139°.
