실험 절차
To 3-bromo-5-bromomethyl-2-methoxy-pyridine (1.42 g, 5.05 mmol) in EtOH (14 mL) and H2O (1.5 mL) was added sodium cyanide (0.25 g, 5.05 mmol), and the reaction was stirred at 50° C. overnight. The mixture was cooled to room temperature and worked up with CH2Cl2 and saturated aqueous NaHCO3. The combined organic layers were dried, filtered, and concentrated to give (5-bromo-6-methoxy-pyridin-3-yl)-acetonitrile.
