実験手順

A mixture of 7.8 parts of ethyl[2-[[3,5-dichloro-4-[(4-chlorophenyl)cyanomethyl]phenyl]hydrazono]-2-cyanoacetyl]carbamate (intermediate 3), 1.98 parts of anhydrous potassium acetate and 120 parts of acetic acid is stirred and heated under reflux for 3 hours. The reaction mixture is concentrated to a volume of 30 parts. Water is added until the product is precipitated. It is sucked off, washed with water and dissolved in trichloromethane. The remaining water is separated and the organic phase is dried, filtered and evaporated, yielding 2-[3,5-dichloro-4-[(4-chlorophenyl)cyanomethyl]phenyl]-2,3,4,5-tetrahydro-3,5-dioxo-1,2,4-triazine-6-carbonitrile (intermediate 4).
