実験手順

Into 10 ml of anhydrous tetrahydrofuran were 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, 0.186 g of methyl 2-[3-(hydroxymethyl)phenoxy]propionate and 0.232 g of triphenylphosphine; 0.179 g of diisopropyl azodicarboxylate was added dropwise under ice-cooling and stirring and the mixture was stirred overnight at room temperature. The reaction solution was concentrated under reduced pressure; the obtained residue was subjected to silica gel column chromatography to give 0.166 g of methyl 2-[3-({2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidine-1-yl]phenoxy}methyl)phenoxy]propionate [Compound 2-1].
