Reaction Steps

In a sealed tube 7-chloro-2-iodofuro[3,2-b]pyridine (0.200 g, 0.72 mmol), KCN (0.093 g, 1.4 mmol), and copper (I) iodide (0.014 g, 0.072 mmol) were dissolved in 2 mL DMF. Pd(Ph3P)4 (0.041 g, 0.036 mmol) was added, the tube was flushed with nitrogen, and the reaction in the tube was stirred overnight at 100° C. The reaction was cooled to RT, diluted with DCM, and washed with water. The aqueous layer was extracted with DCM, and the combined organic layers were washed with brine, dried with sodium sulfate, filtered, and concentrated. The material was purified via column chromatography (gradient elution 0-50% EtOAc:Hex) to afford 7-chlorofuro[3,2-b]pyridine-2-carbonitrile as a white solid. MS: M+H+=179.4.
