4-Iodo-1H-pyrazolo[3,4-b]pyridine (802 mg, 3.27 mmol) was dissolved in DMSO (10 mL) then added p-toluenesulfinic acid, sodium salt (583 mg, 3.27 mmol) and KCN (319 mg, 4.90 mmol). The reaction was heated at 100° C. for 18 h. The mixture was diluted with water and extracted with EtOAc. The organic layer was washed with brine and dried over MgSO4 to yield 1H-pyrazolo[3,4-b]pyridine-4-carbonitrile as a light orange solid.
