실험 절차

To a solution of (4-(7-chloro-1-(2,6-difluorophenyl)-4-oxo-4,5-dihydro-1H-pyrazolo[4,3-c]pyridin-3-yl)phenyl)acetonitrile (134.5 mg) obtained in Example 116 and potassium carbonate (94 mg) in DMSO (2 mL) was added 30% aqueous hydrogen peroxide (139 μL) at room temperature. The reaction mixture was stirred overnight, and poured into water. The precipitated crystals were collected by filtration, and purified by HPLC (C18, mobile phase: water/acetonitrile (containing 0.1% TFA)), to the obtained fraction was added saturated aqueous sodium hydrogencarbonate solution, and the mixture was extracted with ethyl acetate, dried over anhydrous magnesium sulfate, concentrated under reduced pressure, and purified to give the title compound (105 mg).
