실험 절차
1H-pyrazolo[4,3-b]pyridine-5-carboxylic acid, methyl ester (420 mg, 2.37 mmol) was dissolved in THF (30 mL) and cooled to 0° C. LiAlH4 (360 mg, 9.48 mmol) was added in one portion. The mixture was stirred at 0° C. for 3 hr, and diluted with ether. 50% NaOH (5 mL) was added to quench the reaction, and the solid was filtered off through Celite. The filtrate was concentrated, and the residue was purified by flash chromatography to afford 1H-pyrazolo[4,3-b]pyridine-5-methanol (270 mg, 76.4%).
