실험 절차

0.13 g of 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride was added to a mixture of 0.30 g of 3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-carboxymethoxypyridine [present compound 7-6], 56 mg of O-methylhydroxylamine hydrochloride, 68 mg of triethylamine and 2 ml of N,N-dimethylformamide at room temperature, and stirred for 2 hours. Then the mixture was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 90 mg of 3-{2-chloro-4-fluoro-5-[3-methyl-2,6-dioxo-4-(trifluoromethyl)-1,2,3,6-tetrahydropyrimidin-1-yl]phenoxy}-2-[(methoxyaminocarbonyl)methoxy]pyridine [present compound 7-84].
