Sodium azide (715 mg, 11.0 mmol) was added to a solution of the bromide 6 (301 mg, 1.10 mmol) in dry acetone (30 mL). The reaction mixture was stirred at ambient temperature for 1 hour, then heated to reflux for 2 hours. The reaction mixture was then allowed to cool to room temperature, the excess sodium azide was filtered off, and the solvent was removed under reduced pressure to yield the crude azide 7 as a light yellow crystalline solid, which was used immediately in the next step without further purification.
