ABSTRACT:
An improved process for preparing 3-cyclohexyl-1-methyl-6-dimethylamino-s-triazine-2,4(1H,3H)dione by the following reaction sequence: ##STR1## the improvement comprising using R=ethyl, n-propyl or isopropyl, preferably ethyl, thus permitting significantly higher practical overall yields.
Related 3-substituted-1-methyl-6-substituted amino-s-triazine-2,4(1H,3H)diones and 4-thio-2,4(1H,3H)-diones are prepared similarly. These products are useful as herbicides.
