Hydrochloric Acid → 5-azidopentanoic Acid

Temperature

25 °C

To ethyl 5-azidovalerate (1.6 g; 10 mmol; Example 2.1) in 5 ml-dimethylformamide, was added lithium hydroxide (1.0 g; 20 mmol; Fisher) in 5 ml water, and the reaction mixture was stirred 12 h at 25° C. The reaction mixture was adjusted to pH ˜4 by addition of 1 N HCl and was extracted with 100 ml diethyl ether. The resulting organic layer was washed with water (100 ml) and brine (100 ml), dried over sodium sulfate, and dried in vacuo. Yield: 1.4 g (9.8 mmol, 99% yield).
