실험 절차
{1-[6-(4-Benzyloxy-2-fluoro-phenyl)-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridine-4-carbonyl]-4-phenyl-piperidin-4-yl}-carbamic acid tert-butyl ester (90 mg) was dissolved in methanol (2 mL) and purged with argon, then hydrogen. Palladium (10% on charcoal, 13 mg) was added and the mixture was stirred at 38° C. for 2 h. The catalyst was filtered off, the solvent was evaporated and the residue was dissolved in THF (5 mL) containing HCl (4N in dioxane, 0.14 mL). The solution was stirred at r.t. over night, the precipitate formed was filtered off. The filtrate was concentrated, the residue was re-dissolved in methanol/water (v/v=1/1, 4 mL), and concentrated hydrochloric acid (1 mL) was added. The precipitate formed was filtered off, washed with ethyl acetate and acetone and dried in air. The two filtration solids were combined yielding 45 mg (75%) of the title compound.
