Reaction Steps
To a mitre of 3-methoxy-4-nitrobenzyl alcohol (3.00 g) and carbon tetrabromide (8.15 g) in dichloromethane (60 mL) was added triphenylphosphine (5.16 g) under ice-water cooling, and the mixture was stirred for an hour at ambient temperature. After evaporation of the solvent, the residue was purified by a silica gel column chromatography eluting with a mixture of hexane and ethyl acetate (5:1) to give 3-methoxy-4-nitrobenzyl bromide as pale yellow powders (4.87 g).
