Reaction Conditions

Reaction Steps

Dissolve sodium azide (22.84 g, 351.3 mmol) in water (195 mL). Separately, dissolve 2-chloro-3-[[(2S)-oxiran-2-yl]methoxy]pyridine (32.6 g, 175.6 mmol) in 1,4-dioxane (800 mL). Slowly add the water/sodium azide solution to the dioxane solution; heat to 90° C.; and stir for 1 hour. Cool the mixture and concentrate it under reduced pressure. Add water; extract with EtOAc (2×); combine the extracts; dry the combined extracts over Na2SO4; filter; and collect the filtrate. Remove the solvents under reduced pressure to provide the title compound (40.28 g, 92.8%) as a reddish white solid. MS (m/z): 229 (M+1).
