Procedure
To a solution of 9.5 g of 1-(p-prenylphenyl)-ethanol, 4.0 ml of pyridine and 60 ml of benzene, a solution of 5.9 g of thionyl chloride in 10 ml of benzene was added dropwise at 0°-5° C. with stirring. After stirring at room temperature for an hour, the reaction mixture was washed with water, aqueous sodium hydrogen carbonate and water successively and dried. Removal of the benzene gave 10.1 g of 1-chloro-1-(p-prenylphenyl)ethane.
