Procedure

A solution of ethyl 6-bromohexanoate (10.0 g, 44.8 mmol), NaN3 (5.83 g, 89.6 mmol) and 25 ml of water in 75 ml of MeOH was refluxed for 3.5 hrs. The MeOH was removed in vacuo and the residue was partitioned between CHCl3 (200 ml) and water (50 ml). The organic layer was separated and washed with water. After drying (Na2SO4) and evaporation of solvent, ethyl 6-azidohexanoate (8.59 g, 100%) was obtained as a colorless oil.
