Versuchsvorschrift

To a suspension of N-(4-((2-aminopyridin-4-yl)oxy)-2-chlorophenyl)-1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamide (125 mg, 0.28 mmol) and Et3N (0.12 mL, 0.84 mmol) in THF (4.0 mL) was added phenyl carbonochloridate (0.10 mL, 0.84 mmol). The mixture was stirred at rt for 2 hours, then morpholine (0.15 mL, 1.68 mmol) was added. The resulted mixture was stirred rt for 22 hours, then partitioned between aqueous NH4Cl solution (20 mL) and DCM (20 mL). The organic phase was separated and the aqueous phase was extracted with DCM (20 mL×3). The combined organic phases were dried over anhydrous Na2SO4, and concentrated in vacuo. The residue was purified by a silica gel column chromatography (EtOAc/PE (v/v)=20/1), followed by washing with methanol (4 mL) to give the title compound as a beige solid (60 mg, 38%).
