실험 절차
To a solution of 3-bromo-4-chloro-5-fluoro-pyridine (7.56 g, 32.18 mmol) in pentane (100 mL) was added hydrogen chloride (2M in ether) (17.7 mL of 2 M, 35.4 mmol). An off-white precipitate formed instantly. The mixture was stirred for 5 minutes then the solid was collected by filtration, washed with pentane and dried by suction to afford the desired product as an off-white solid (4.79 g, 60%). 1H NMR (DMSO-d6) δ 8.77 (s, 1H), 8.75 (s, 1H).
