To 2-(3-(1H-pyrazolo[3,4-b]pyridin-4-yl)phenyl)-2-methylpropanenitrile (22 mg, 0.084 mmol) was added slowly a 2 M solution of lithium aluminium hydride (167.70 ml, 0.336 mmol) in tetrahydrofuran (3 ml). The reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was allowed to cool down to room temperature and was partitioned between water and ethyl acetate. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by reverse phase preparative HPLC [Waters Sunfire C18, 10 μM, 100 Å column, gradient 10%-95% B (solvent A: 0.05% TFA in water; solvent B: CH3CN) over 16 minutes at 25 mL/min]. The fractions were freeze-dried to give the title compound as a white solid (12 mg, 54% yield).
