Procedure

To a solution of 148 parts of said methyl N-(1-amino-1-methylthiomethylene)carbamate in 2,000 parts methylene chloride is added 154 parts of 4-chlorophenyl isocyanate. The reaction is stirred overnight. Then to it is added 54 parts of sodium methoxide in 540 parts of methanol. The reaction mixture is then refluxed for one hour. The reaction mass is cooled, and 2,000 parts of ether are added. The solid collected by filtration is dissolved in water and the solution neutralized with hydrochloric acid. The new solid thus formed is collected, dried, and recrystallized from ethanol/H2O to give 140 parts of 3-(4-chlorophenyl)-6-methylthio-s-triazine-2,4-(1H,3H)-dione melting at 292°-295° C.
