DPPA (0.55 mL, 2.55 mmol) was added to (S)-1-(5-(prop-1-en-2-yl)pyridin-3-yl)ethanol (347 mg, 2.13 mmol) in toluene (5 mL) and the reaction is cooled to 0° C. DBU (0.38 mL, 2.55 mmol) was added, the reaction was allowed to warm to room temperature and stirred overnight, diluted with EtOAc and washed with water. The organic layer was dried with Na2SO4 and concentrated under reduced pressure. The residue was purified by column chromatography (35% EtOAc in hexanes) to provide 340 mg of (R)-3-(1-azidoethyl)-5-(prop-1-en-2-yl)pyridine.
