Reaction Steps

To a solution of 4-(3-bromo-prop-1-ynyl)-phenol (5.0 g, 30.12 mmol) dissolved in dichloromethane, 8.3 g (31.63 mmol, 1.05 eq) of triphenylphosphine was added and the solution was cooled to 0° C. Bromine (1.55 mL, 30.12 mmol, 1.0 eq) was added dropwise and the reaction was warmed to room temperature. The reaction was then diluted with dichloromethane, washed with sodium hydrosulfite pentahydrate, washed with brine, dried over MgSO4 and concentrated. The residue was purified via flash chromatography using 4:1 hexane:ethyl acetate to afford 5.56 g (80%) of 1-(3-bromo-prop-1-ynyl)-4-chloro-benzene as an amber oil. Electrospray Mass Spec 280.4 (M+H)+.
