Reaktionsschritte

To a solution of 1.2 g of the alcohol compound obtained in 20 ml of acetonitrile were added 1.2 g of 1,1'-carbonyldiimidazole and 2.5 ml of allyl bromide. The mixture was stirred for 2 hours at room temperature and then heated under reflux for 1.5 hours. After cooling, water was added to the reaction mixture, and the mixture was extracted with diethyl ether. The ethereal layer was washed with a saturated sodium chloride aqueous solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain 1.1 g of 4,4-ethylenedioxy-4-phenylbutyl bromide as colorless crystals.
