Versuchsvorschrift

A mixture of 15.16 g of 2-(methoxycarbonyl)methoxyphenol, 29.23 g of 2,5-difluoro-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]nitrobenzene (produced in Intermediate Production Example 4), 11.5 g of anhydrous potassium carbonate and 160 ml of N,N-dimethylformamide was stirred at room temperature for 30 minutes, and then, stirred at 70° C. for 3 hours. To the mixture, 5 g of 2-(methoxycarbonyl)methoxyphenol was added and stirred for 1 hour. The reaction solution was poured into 2% of aqueous hydrochloric acid solution and extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 17.8 g of 2-{2-(methoxycarbonyl)methoxyphenoxy}-5-fluoro-4-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]nitrobenzene [Compound 4-19 of the present invention].
