Reaction Steps
To a solution of methyl 2-(5-aminopyridin-2-yl)acetate (0.250 g, 1.5 mmol) in THF (20 mL) at 0° C. was added lithium aluminum hydride (1.0 M, 3.75 mL, 3.75 mmol). The mixture was warmed to rt and stirred for 2 h. After this time, the reaction was quenched with water and NaOH (2 M), dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, dichloromethane/methanol) to afford the title compound (0.046 g, 22%) as an orange oil. MW=138.17. 1H NMR (CDCl3, 500 MHz) δ 8.01-7.97 (m, 1H), 6.97-6.92 (m, 2H), 3.96 (t, J=5.5 Hz, 2H), 3.60 (s, 2H), 2.89 (t, J=5.5 Hz, 2H); APCI MS m/z 139 [M+H]+.
