Reaction Steps
Ethyl (3-Iodo-pyrazolo[3,4-b]pyridin-1-yl)-acetate (11 g, 33 mmol, 1 equiv) was dissolved in 50 mL of THF and 50 mL of MeOH to the solution was added 40 mL of 1N LiOH for 3 h. The organic solvents were evaporated and the remaining aqueous phase was neutralized with 1N HCl to a pH of about 1 which resulted in the precipitation of the desired product as a white solid was filtered and air dried to give (3-iodo-pyrazolo[3,4-b]pyridin-1-yl)-acetic acid.
