Reaction Steps

To a stirred solution of (S)-tert-butyl (2-azido-1-(3-bromo-5-fluorophenyl)ethyl)carbamate (3.15 g, 8.77 mmol) in dioxane (40 mL) was added hydrochloric acid (10.96 mL, 43.8 mmol) (4N solution in dioxane). The reaction was heated to 40° C. and maintained at this temperature for 2 h. After cooling the reaction mixture was evaporated to dryness, giving (S)-2-azido-1-(3-bromo-5-fluorophenyl)ethanamine hydrochloride (2.59 g, 8.76 mmol, 100% yield) as a white solid.
