실험 절차
To a stirred suspension of 2-amino-4,6-dimethyl-1,3,5-triazine in 10 parts by volume of nitroethane at -10° to 0° is added dropwise an equivalent amount of chlorosulfonyl isocyanate. The mixture is stirred for one hour at -10° allowing for completion of the reaction to form [(4,6-dimethyl-1,3,5-triazin-2-yl)aminocarbonyl]sulfamoyl chloride. The additional reagent such as pyrrole is then added and the preparation of the stable herbicidal compound is continued as described in Example 2 or for Equations 3 and 3A.
