Reaction Steps

Benzyl 3-{3-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-2-ethoxy-6-methylphenyl}azetidine-1-carboxylate (170 mg, 0.32 mmol, racemic intermediate) and 5% palladium (80 mg) were combined in methanol (12 mL), to which was added 0.25 M hydrogen chloride in water (3.2 mL, 0.79 mmol). The suspension was hydrogenated under balloon pressure of H2 at room temperature for 2 h. The suspension was filtered. The filtrate was neutralized with sat. NaHCO3 solution, and extracted with dichloromethane. The combined organic layers were dried over MgSO4 and filtered, concentrated to give the desired product (117 mg, 92%). LCMS calculated for C20H26ClN6O (M+H)+: m/z=401.2; Found: 401.1.
