Procedure

A mixture of 2-chloro-4-cyanophenol (2.15 g), 3-bromo-1-chloropropane (2.3 g), dimethylformamide (3 ml) and potassium carbonate (1.5 g) was heated at 100° C. for one hour. After the inorganic salt was filtered off, the solvent was distilled off and the residue was dissolved in chloroform. The solution was chromatographed on a column of silica gel (80 g) and eluted with a solution of petroleum ether-ethyl acetate (10:1) to give 3.06 g of 3-(2-chloro-4-cyanophenoxy)propyl chloride as a colorless oil.
