Versuchsvorschrift

To a solution of 4-((6-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamido)pyridin-3-yl)oxy)picolinamide (60 mg, 0.13 mmol) in EtOAc/MeCN/H2O (2 mL/2 mL/1 mL) was added iodobenzene diacetate (54 mg, 0.16 mmol) at 0° C. The reaction was stirred at rt for 2 hours, then concentrated in vacuo. The resulted residue was dissolved in EtOAc (10 mL), washed with saturated aq. NaHCO3, and then dried over anhydrous Na2SO4. The organic solution was concentrated in vacuo to give the title compound as a yellow solid (43 mg, 77%).
