Versuchsvorschrift

4-Ethoxybenzyl alcohol (5 g) and concentrated hydrochloric acid (8.5 cm3) were vigorously stirred together for 30 minutes. The 2 phases were then allowed to separate, and the lower layer separated off, and diluted with chloroform. The organic solution was dried over anhydrous magnesium sulphate, and removal of the solvent by evaporation gave 4-ethoxybenzyl chloride (5.6 g). (This product is not stable on keeping, so was converted immediately to the phosphonium salt--see Example 12).
