Reaction Steps

6-Methyl-1-(phenylmethyl)-1H-pyrazolo[3,4-b]pyridine-4-carbonitrile (1 g), sodium hydroxide (0.805 g, 20.14 mmol), ethanol (25 mL) and water (10 mL) were heated at reflux for 2 hours. After cooling to room temperature, the solvent was removed under reduced pressure. The crude product was suspended in water (50 mL) and acidified by dropwise addition of 6N HCl. The solid product was filtered off and dissolved in 100 ml of EtOAc. The solution dried over MgSO4, filtered, and concentrated in vacuo. The final product was obtained as 0.730 g. LCMS E-S (M+H)=267.9. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.71 (s, 3 H), 5.70 (s, 2 H), 7.15-7.37 (m, 5 H), 7.63 (s, 1 H), 8.33 (s, 1 H), 13.86 (s, 1 H).
