To a solution of 2-chloropyridin-4-amine (2.0 g, 15.6 mmol) in DMF (20 mL) under nitrogen was added NaN3 (2.0 g, 31.2 mmol) and NH4Cl (1.7 g, 31.2 mmol). The mixture was heated to 110° C. for 10 hours and then quenched with saturated Na2CO3. The reaction was filtered and then the filtrate was extracted with ethyl acetate (3×20 mL). The combined organic extracts were washed with water (50 mL), dried over Na2SO4, and concentrated under reduced pressure to afford 2-azidopyridin-4-amine (1.5 g, yield: 83%). LCMS (ESI) m/z: 136.2 [M+H+].
