실험 절차

To a mixture of 1-(2-cyclopropyl-3-methyl-2H-indazol-5-yl)-4-hydroxypyridin-2(1H)-one (200 mg) and 2-(chloromethyl)-4-(trifluoromethyl)thiophene (171 mg) in DMF (4 ml) was added potassium carbonate (118 mg) at room temperature, and the mixture was stirred at the same temperature overnight. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was fractionated by HPLC (C18, mobile phase: water/acetonitrile (containing 0.1% NH4HCO3)), and saturated aqueous sodium hydrogen carbonate solution was added to the obtained fraction. The mixture was extracted with ethyl acetate, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was crystallized from methanol-water to give the title compound (152 mg).
