Under N2, a solution of 7.33 g (40.7 mmol) of 3-(3-methoxy-4-methylphenyl)-1-propanol in 200 mL of CH2Cl2 was treated with 10.67 g (40.7 mmol) of triphenylphosphine followed in portions by 7.3 g (40.7 mmol) of recrystallized N-bromosuccinimide. The solution was stirred at room temperature for 2 hours, then filtered through flash silica gel. Removal of the solvent under reduced pressure left 8.68 g (87.9% yield) of the product as a clear oil. The structure was confirmed by NMR spectroscopy.
