Procedure

A suspension of 5.0 g of 3-[4-chloro-3-iodophenyl]-2,4-dioxo-1-methyl-6-trifluoromethyl-1,2,3,4-tetrahydropyrimidine, 2.0 g of 2,2,2-trifluoroethyl acrylate, 0.5 mg of palladium acetate and 1.1 g of sodium acetate in 50 ml of dimethylformamide was stirred for 4 hours at 120° C., after which further palladium acetate and 2,2,2-trifluoromethyl acrylate were added and stirring was continued for a further 2 hours at 120° C. The cooled reaction mixture was added to 200 ml of water and the precipitate was isolated, washed with petroleum ether and dried under greatly reduced pressure.
