Phosphorus tribromide → 1-(Benzyloxy)-4-(bromomethyl)benzene

Participants

Reaction Conditions

Reaction Steps

To a solution of (4-(benzyloxy)phenyl)methanol (21.4 g, 100 mmol) in diethyl ether (250 mL) at 0° C. was added phosphorous tribromide (10.8 g, 40 mmol) and stirred at 0° C. for minutes and at room temperature for 3 hours. The reaction was quenched with water and the layers were separated. The organic layer was washed with water (2×400 mL), saturated sodium bicarbonate (2×400 mL), and brine. The ether layer was dried over sodium sulfate, filtered and concentrated in vacuo to afford 1-(benzyloxy)-4-(bromomethyl)benzene (746).
