実験手順

A mixture of ethyl{[5-(3-{[(3-methylpyridin-2-yl)carbonyl]amino}phenoxy)pyridin-2-yl]carbamothioyl}carbamate (2.00 g, 4.43 mmol), hydroxylammonium chloride (3.13 g, 45.0 mmol), N,N-diisopropylethylamine (4.70 mL, 26.9 mmol), ethanol (50 mL) and methanol (50 mL) was stirred at 80° C. for 5 hr. The reaction solution was concentrated under reduced pressure, and ethyl acetate was added to the residue. The mixture was washed with aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous magnesium sulfate and filtrated. The filtrate was concentrated under reduced pressure, and the residue was washed with ethyl acetate to give the title compound (1.35 g, 84%) as a white solid.
