Reaction Steps

To a solution of methyl 3-(1H-pyrazolo[3,4-b]pyridin-5-yl)benzoate (1.65 g, 6.52 mmol) in dichloroethane (40 mL) was added NIS (1.81 g, 8.04 mmol) and the mixture was stirred at 70° C. for 6 hours. The solvent was removed by reduced pressure and the crude product was purified by silica gel chromatography to afforded methyl 3-(3-iodo-1H-pyrazolo[3,4-b]pyridin-5-yl)benzoate (9) (988 mg, 40% yield). MS: m/z 379.9 (M+H+).
