실험 절차

To a suspension of 1-(2,3-dimethyl-2H-indazol-5-yl)-4-hydroxypyridin-2(1H)-one (65 mg), [4-(trifluoromethyl)-1,3-thiazol-2-yl]methanol (73 mg) and triphenylphosphine (156 mg) in tetrahydrofuran (6 ml) was added bis(2-methoxyethyl)azodicarboxylate (140 mg) at room temperature, and the mixture was stirred at the same temperature for 3 hr. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate/methanol) and recrystallized from 2-propanol-diisopropyl ether to give the title compound (42 mg).
