Procedure

Into 10 ml of N,N-dimethylformamide was dissolved 0.3 g of 2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidine-1-yl]phenol; 0.159 g of anhydrous potassium carbonate was added; 0.305 g of ethyl 2-[2-(bromomethyl)phenoxy]propionate was added at room temperature under stirring and the mixture was stirred overnight at room temperature. The reaction solution was poured into a mixture of ice and a saturated aqueous ammonium chloride solution and the mixture was extracted twice with ethyl acetate. The organic layers were combined and washed once with a saturated aqueous ammonium chloride solution and once with saturated aqueous sodium chloride solution in turn, dried over magnesium sulfate and then concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography to give 0.35 g of ethyl 2-[2-({2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidine-1-yl]phenoxy}methyl)phenoxy]propionate [Compound 3-2].
