실험 절차

1.6 g of thionyl chloride were added to a solution of 4.5 g of 3-[3-(2-bromo-2-carboxyethenyl)-4-chlorophenyl]-2,4-dioxo-1-methyl-6-trifluoromethyl-1,2,3,4-tetrahydropyrimidine and 0.1 ml of dimethylformamide in 100 ml of toluene. The reaction mixture was heated slowly to the reflux temperature, stirred under reflux for 5 hours and evaporated down, and the residue was dried under greatly reduced pressure.
