실험 절차

A mixture of ethyl ({[5-(3-{[(1,3-dimethyl-1H-pyrazol-5-yl) carbonyl]amino}-4-fluorophenoxy)pyridin-2-yl]amino}carbonothioyl)carbamate (1.15 g, 2.43 mmol), hydroxylammonium chloride (1.18 g, 17.0 mmol), N,N-diisopropylethylamine (2.12 mL, 12.2 mmol), ethanol (10 mL) and methanol (10 mL) was stirred at 80° C. for 8 hr. The reaction mixture was diluted with water and extracted with ethyl acetate (×3). The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and filtrated. The filtrate was concentrated under reduced pressure, and the residue was collected by filtration and washed with ethyl acetate-hexane to give the title compound (650 mg, 70%) as a yellow solid.
