Reaction Steps

Ethyl 6-azidohexanoate (8.59 g, 44.8 mmol) and KOH (13.0 g, 0.231 mol) were dissolved into a mixture of 120 ml of water and 180 ml of MeOH. The solution was stirred at 0° C. for 2 hrs then MeOH was removed in vacuo. The aqueous layer was extracted by CHCl3 (2×10 ml), acidified to pH=1 by 2N aqueous HCl and extracted by Et2O (2×100 ml). The organic layers were combined, washed with water (100 ml) and dried over Na2SO4. After-filtration and evaporation of solvent, 6-azidohexanoic acid (6.56 g, 93%) was obtained as a colorless oil.
