Reaction Steps
To a solution of ((2R)-7-chloro-8-o-tolylchroman-2-yl)methyl 4-methylbenzenesulfonate (0.8 g, 1.8 mmol) in DMSO (50 mL) was added sodium azide (1.2 g, 18.4 mmol) and the resulting mixture was heated at 60° C. overnight. The mixture was extracted with ethyl acetate, washed with water and saturated sodium chloride, dried with anhydrous sodium sulfate and concentrated under reduced pressure. Purification by ISCO using a solvent gradient of 0 to 20% ethyl acetate in hexanes provided 0.5 g (88%) of (2R)-2-(azidomethyl)-7-chloro-8-o-tolylchroman as a colorless oil.
