Reaction Steps

To a solution of 2-(4-bromophenyl)ethanol (1.00 g) and tetrabromomethane (3.96 g) in tetrahydrofuran (10 ml) was added triphenylphosphine (2.87 g) at room temperature and the mixture was stirred at the same temperature for 1 hour under nitrogen. The mixture was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give 1-bromo-4-(2-bromoethyl)benzene (2.07 g).
