Reaction Steps

To a solution of 1H-pyrazolo[3,4-d]pyrimidin-4-ylamine (3.0 g, 22.20 mmol, 1.0 eq) in DMF (30 mL), NIS (6.7 g, 24.42 mmol, 1.1 eq) was added at room temperature. The reaction mixture was stirred overnight at 60° C. The reaction mixture was cooled to room temperature and 10% aq. NaHCO3 (150 mL) was added to the reaction mixture. The solid was filtered and re-crystallization from DMF solvent to give 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (4.0 g, 69% in yield).
