Versuchsvorschrift
A solution of 2-methoxyisopropyl-benzene (2 g) and N-bromosuccinimide (2.6 g) in acetonitrile (20 mL) was stirred at ambient temperature for 18 h. The reaction was concentrated in vacuo, slurried in carbon tetrachloride and filtered. The filtrate was concentrated in vacuo. The residue was flash chromatographed (5% dichloromethane/hexanes) to afford the title compound as an oil (2.5 g).
