2.7 g of 2-difluoromethoxybenzenesulfonylisocyanate are added to a solution of 2.54 g of 2-amino-4-cyclopropyl-6-trichloromethyl-1,3,5-triazine, and the whole is stirred at room temperature for 14 hours. Hexane is then added until the reaction product precipitates. Filtration is carried out and the filtration residue is dried to thus obtain 3 g of the above urea, which melts at 103°-105° C.
