Cl[CH2:2][CH2:3][CH2:4][CH:5]([O:11][C:12](=[O:14])[CH3:13])[CH2:6][CH2:7][CH2:8][CH2:9][CH3:10].[I-:15].[Na+]>CC(C)=O>[I:15][CH2:2][CH2:3][CH2:4][CH:5]([O:11][C:12](=[O:14])[CH3:13])[CH2:6][CH2:7][CH2:8][CH2:9][CH3:10]A mixture of 1-chloro-4-acetoxynonane (Ex. 1, Step B-3) (35.3 g., 0.16 mole) and sodium iodide (120 g., 0.8 mole) in acetone (350 ml.) is stirred and heated at reflux with exclusion for light for 10 hours. The resulting suspension is filtered and the collected sodium chloride washed with acetone. The combined filtrate and washings are evaporated in vacuo leaving a residual mass which is partitioned between ether and water. The organic extract is washed with dilute aqueous sodium thiosulfate and water, dried over sodium sulfate and evaporated in vacuo providing the title compound as a colorless liquid (48.7 g., 98%), pmr (CDCl3) δ 2.0 (s, 3H), 3.18 (t, 2H) and 4.98 (m, H).
