실험 절차
A mixture of 2-bromopyridin-3-ol 27 (0.1 mmol), 1-bromo-2-fluoroethane (0.2 mmol) and K2CO3 (0.4 mmol) in acetonitrile were stirred at refluxing for one day until TLC indicated that the reaction was complete, and then filter, dried and concentrated under reduce pressure. The crude product was purified with column chromatography to afforded 28 (yield, 68%). 1H NMR (CDCl3): δ 4.25-4.34 (m, 2H), 4.73-4.89 (m, 2H), 7.20-7.22 (m, 2H), 8.01 (s, 1H).
