Procedure

Thionyl chloride (1.49 g, 12.6 mmol) was added to 1-(2-chlorophenyl)ethanol (1.0 g, 6.3 mmol) in toluene (50 mL) and the mixture was allowed to stir at room temperature for 2 h. To the reaction mixture was added 10% aq. HCl solution (20 mL). The organic phase was separated and washed with another portion of 10% aq. HCl solution, brine (20 mL) and then separated, dried and evaporated to provide 1-chloro-2-(1-chloroethyl)benzene in 72% yield.
