Procedure

2,4-Dichlorobenzyl chloride (23.45 g) and potassium iodide (47.88 g) are stirred in acetone (100 ml) at room temperature for 24 hours. After concentrated, this is extracted with t-butyl methyl ether (300 ml) and water (100 ml). The extract is washed with water, dried and concentrated to obtain 2,4-dichlorobenzyl iodide (34.49 g).
