Carbon tetrabromide → 3-Methoxy-4-nitrobenzyl bromide

Participants

Reaction Conditions

Reaction Steps

A solution of 4-nitro-3-methoxybenzyl alcohol (1.0 g, 5.46 mmol) in THF (5 ml) was cooled to 0° C. and carbon tetrabromide (3.62 g, 10.92 mmol) and triphenylphosphine (1.57 g, 6.00 mmol) were added. The reaction mixture was stirred at 0° C. for 2 hours then the solvents were removed under reduced pressure. The residue was purified by column chromatography on neutral silica gel using 5-8% EtOAc in hexane to give the title compound (1.25 g, 93%).
