Reaction Steps

To a stirred suspension of lithium aluminum hydride (8.8 mg) in diethyl ether (0.5 ml) was added a solution of ethyl 4-(5-bromo-3-pyridyl)-1-ethyl-6-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (30 mg) in diethyl ether (1.5 ml) at −78° C. The mixture was gradually warmed to −10° C. over 8 hours and quenched with water at −10° C. The mixture was filtered through celite pad, and the filtrate was evaporated. The residue was purified by preparative thin layer chromatography eluting with a mixture of EtOAc and n-hexane (2:1) to give [4-(5-bromo-3-pyridyl)-1-ethyl-6-methyl-1H-pyrazolo[3,4-b]pyridin-5-yl]methanol (18 mg) as a colorless crystal.
