실험 절차

Ethyl 4-azidobutyrate (8.06 g, 51.3 mmol) and KOH (14.4 g, 0.256 mol) were dissolved into a mixture of 100 ml of water and 120 ml of MeOH. The solution was stirred at 0° C. for 2 hrs and then MeOH was removed in vacuo. The aqueous layer was extracted by CHCl3 (50 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, 4-azidobutyric acid (5.30 g, 80%) was obtained as a colorless oil.
