furo[3,2-b]pyridine

272-62-8

PdCl2(PPh3)2 (1.4 g, 2.0 mmol) and CuI (0.4 g, 2.1 mmol) were dissolved in a solvent mixture of triethylamine (TEA, 100 mL) and tetrahydrofuran (THF, 200 mL) under nitrogen atmosphere. Subsequently, a solution of 2-bromo-3-acetoxypyridine (13.1 g, 60.6 mmol) and trimethylsilylacetylene (TMS-acetylene, 7.0 g, 71 mmol) in THF (100 mL) was added one time to the above solution. The reaction mixture was stirred at room temperature for 1 hour. Upon completion of the reaction, the reaction was quenched with saturated sodium bicarbonate solution (50 mL) and methanol (50 mL). The mixture was continued to be stirred at 80 °C for 2 hours. After cooling to room temperature, it was extracted with ether. The organic phases were combined, dried over anhydrous sodium sulfate and concentrated under reduced pressure to remove the solvent. The residue was purified by column chromatography to afford furo[3,2-b]pyridine (1.54 g, 21% yield).1H NMR (CDCl3, 400 MHz) δ 8.55 (m, 1H), 7.84 (m, 1H), 7.75 (m, 1H), 7.72 (m, 1H), 6.99 (m, 1H).
