2-Bromocyclohexan-1-one (K. Tanemura, T. Suzuki, Y. Nishida, K. Satsumabayashi, T. Horaguchi, Chem. Commun. 2004, 470-471) (0.55 g, 3.11 mmol) was dissolved in DMSO (3 mL). Sodium azide (1.00 g, 15.5 mmol) was added, and the resulting mixture was stirred for 2 h. The solution was then diluted with water (50 mL) and extracted with diethyl ether (2×20 mL). The organic layers were combined, washed with water (2×20 mL), dried over Na2SO4(s), filtered, and concentrated under reduced pressure. The resulting oil was found to be pure by NMR analysis and was used without further purification (0.40 g, 2.87 mmol, 92% yield).
