Procedure
0.48 g of 3-[3-amino-4-chloro-6-fluoro-2-hydroxyphenyl]-1-methyl-6-trifluoromethyl-2,4-(1H,3H)-pyrimidinedione (from intermediate 7) was initially charged with 0.14 g of triethylamine in 30 ml of absolute xylene, and the mixture was, at 0° C., admixed dropwise with 0.18 g of cyclopentanecarbonyl chloride. After 10 minutes, the mixture was warmed to 20° C., 0.1 g of pyridinium p-toluenesulfonate was added and the mixture was heated at reflux for six hours. After cooling, the xylene phase was washed three times with 30 ml of water each time, dried over sodium sulfate and freed from the solvent under reduced pressure. The crude product was purified by medium pressure liquid chromatography (MPLC); mobile phase: cyclohexane/ethyl acetate (9:1). Yield: 0.27 g;
