Procedure

To a solution of N-bromo succinimide (8.6 g, 48.48 mmol) in chloroform (60 mL) was added 1-fluoro-4-isopropenyl-benzene (6 g, 44.11 mmol) at RT. The reaction mixture was stirred at 60° C. for 15 h. The progress of reaction was monitored by TLC. The reaction mixture was cooled to RT and filtered. The residue was rinsed with DCM (50 mL). The combined filtrate was concentrated under reduced pressure to obtain crude product that was purified by column chromatography using silica (100:200) and pure hexane to yield 4.2 g of 1-(1-bromomethyl-vinyl)-4-fluoro-benzene.
