실험 절차

5-(Benzyloxy)pyridin-2-amine hydrochloride (52.3 g, 221 mmol) and sodium acetate (45.3 g, 552 mmol) were dissolved in acetic acid (300 mL). Bromine (11.3 mL, 221 mmol) was added slowly and stirred at ambient temperature for 18 hours. After an aqueous workup, the material was purified over silica gel to give the title compound (10.5 g, 17.0% yield).
