実験手順
To a stirred mixture of 16 parts of 2-[3-chloro-4-[(2.4-dichlorophenyl) hydroxymethyl]phenyl]-1,2,4-triazine-3,5(2H,4H)-dione and 150 parts of trichloromethane are added dropwise, during a period of 5 minutes, 16 parts of thionyl chloride. Upon completion, stirring is continued for 3 hours at reflux temperature. The reaction mixture is 10 evaporated in vacuo. Methylbenzene is added and the whole is evaporated again, yielding 2-[3-chloro-4-[chloro(2,4-dichlorophenyl) methyl]phenyl]1,2,4-triazine-3,5(2H,4H)-dione.
