Reaction Steps
To a solution of 2-Amino-5-bromo-1-ethoxycarbonylmethyl-pyridinium; bromide (2.86 g, 8.4 mmol) in methanol (30 mL) was added sodium methoxide (25 wt %, 2.5 mL, 10.1 mmol). The reaction mixture was stirred at room temperature overnight under argon. The reaction mixture was diluted with water and then extracted three times with ethyl acetate. The organic extracts were washed with brine, dried over magnesium sulfate, filtered, evaporated to yield a tan solid. The crude material was purified by column chromatography eluting with 3, 5, and 10% methanol/dichloromethane. The product was obtained as a brown solid (56 mg, 3%). 1H NMR (CDCl3) δ 7.85 (s, 1H), 7.67 (dd, J=1.6, 9.5 Hz, 1H), 7.07 (d, J=9.5 Hz, 1H), 4.52 (s, 2H); MS (m/e): 215 (MH+); HRMS: calc'd MH+ for C7H5BrN2O 212.9672; found 212.9664.
