Reaction Steps
To a solution of dimethyl carbonate (2.14 g, 23.7 mmole) and sodium methoxide (1.0 mL, 4.5 mmole. 25% wt in CH3OH) in CH3OH (25 mL) was added 2-amino-5-bromo-3-(methylaminomethyl)pyridine (1.0 g, 4.62 mmole). The reaction was heated at 50° C. overnight, diluted with H2O (1 mL) and concentrated. Toluene was added to the reaction residue and the contents were heated to reflux for 12 hr under a Dean-Stark apparatus. The reaction was cooled to RT, diluted with EtOAc, and washed with H2O. Purification on Silica gel (9:1 CHCl3/CH3OH containing 5% NH4OH) gave the title compound (0.75 g, 67%) as an off-white solid: MS (ES) m/e 243 (M+H)+.
