Sodium Azide → HCID 86590310, compound

Participants

Reaction Steps

To a stirred solution of cis-1-(tert-butoxycarbonylamino)-4-chloro-2-cyclohexene (1.85 g, 8.00 mmol) in DMF (40 mL) was added sodium azide (1.17 g, 18.0 mmol) and the resultant mixture was stirred at room temperature for 16 hours. The reaction mixture was poured into brine (40 mL) and diluted with ethyl acetate (120 mL) and water (20 mL). The phases were separated and the organic phase was washed with brine (4×25 mL). The organic phase was dried (MgSO4), and concentrated. Purification of the crude material by column chromatography on silica gel (10:1 hexanes-ethyl acetate) provided 1.14 g (60%) of trans-1-azido-4-(tert-butoxycarbonylamino)-2-cyclohexene as a colorless oil.
