Versuchsvorschrift
A solution of 2-trifluoromethyl benzyl alcohol (1 g, 5.67 mmol) in aqueous HBr (6 mL) was stirred at 50° C. for 4 hrs. The reaction mixture was diluted with cold water and the product extracted with ethyl acetate. The organic layer was washed with saturated brine solution, dried over sodium sulphate and concentrated to afford 780 mg of 2-trifluoromethylbenzyl bromide.
