Versuchsvorschrift

To a solution of 3-allyloxybenzyl alcohol (7.2 g) in dichloromethane (100 ml) at 0° C. was added thionyl chloride (4.8 ml) in dichloromethane dropwise and a drop of DMF and the mixture stirred at ambient temperature for 1.5 hours, and poured into cold sodium bicarbonate solution. The organic layer was washed with sodium bicarbonate (2×100 ml), dried (magnesium sulphate), filtered and evaporated to give 3-allyloxybenzyl chloride (8.3 g).
