Reaction Steps

To a solution of ethyl 3-bromo-1-isopropyl-6-(4-(morpholinomethyl)phenyl)-1H-pyrazolo[3,4-b]pyridine-4-carboxylate (1 g, 2.05 mmol) in EtOH (15 mL), aqueous NaOH (0.123 g, 3.08 mmol) was added and reaction mixture stirred at 60° C. for 1 h. After completion of the reaction, ethanol was removed under reduced pressure and it was acidified using 10% citric acid solution. Solid obtained was filtered and azeotrope it with toluene to give the desired compound (0.8 g, 84.9%).
