実験手順

4-[1-(4-Methoxybenzyl)-1H-pyrazolo[3,4-b]pyridin-4-yloxy]aniline (263 mg) was dissolved in TFA (7.5 mL). The resulting mixture was stirred at 60° C. for 2 hours and concentrated under reduced pressure. The residue was diluted with dichloromethane and then washed with a sodium bicarbonate solution and saturated brine. The organic layer was separated and concentrated under reduced pressure. The residue was suspended in ether, and the precipitate was collected by filtration to give 4-(1H-pyrazolo[3,4-b]pyridin-4-yloxy)aniline (151 mg, yield: 88%) as a light-brown powder.
