A solution of 5-bromovaleronitrile (48.6 g, 0.3 mol) in N, N-dimethylformamide (600 ml) was treated with sodium azide (23.4 g, 0.36 mol) and stirred at 100° C. for 4 h. The reaction mixture was cooled to 23° C. and diluted with water (500 ml); the resulting solution was extracted with ether (4×400 ml). The ether extracts were combined, washed with water (3×200 ml) and dried over anhydrous magnesium sulfate. The evaporation of ether under reduced pressure gave a yellow liquid which was distilled under high vacuum; bp 83°-4° C.
