A mixture of (5-bromo-pentyl)-cyclohexane (2 gm, 8.58 mmol) in acetone (20 ml), and sodium iodide (2.57 g, 17.15 mmol) was heated at 60° C. for 12 hrs and then cooled to room temperature. The solvent was evaporated, the residue was taken up in EtOAc (30 ml), washed with water (20 ml) and then brine (30 ml). The organic layer was separated, dried over anhydrous sodium sulfate and solvent was removed under reduced pressure. The crude product was purified by column chromatography using hexane as an eluent to yield an oily liquid (1.36 gm). 1H NMR (CDCl3): δ 0.8 (t, 2H, J=10.2 Hz), 1.00-1.38 (m, 9H), 1.52-168 (m, 6H), 1.70-1.80 (m, 2H), 3.10 (t, 2H, J=6.9 Hz).
