Reaction Conditions

Reaction Steps

7-Chloro-2-iodofuro[3,2-b]pyridine (0.130 g, 0.47 mmol), cyclopropylboronic acid (0.080 g, 0.93 mmol), and tricyclohexylphosphine (0.026 g, 0.093 mmol) were dissolved in 3 mL toluene and 1 mL water. Potassium phosphate (0.30 g, 1.4 mmol) was added followed by PdOAc2 (0.010 g, 0.047 mmol), the reaction was flushed with argon, and the reaction stirred at 100° C. for 48 h. The reaction was cooled to RT and partitioned between DCM and water. The layers were separated and the aqueous layer was extracted with DCM. The combined organic layers were dried with sodium sulfate, filtered, and concentrated. The crude material was purified via column chromatography (gradient elution 0-50% EtOAc:Hex) to afford 7-chloro-2-cyclopropylfuro[3,2-b]pyridine as an orange oil. MS: M+H+=194.4.
