Carbon tetrabromide → Methyl 2-(4-bromomethylphenoxy)-3-phenylpropanoate

Participants

Reaction Steps

To a cooled (0° C.) solution of 0.230 g (0.80 mmol) of the product of Step D dissolved in 4 mL of CH2Cl2 was added 0.263 g (1.00 mmol) of carbon tetrabromide and 0.333 g (1.00 mmol) of triphenylphosphine. After 15 minutes at 0° C., the reaction mixture was allowed to warm to room temperature and was stirred for an additional 6 hours. The reaction was then concentrated in vacuo and purified on a silica gel flash chromatography column eluted with 5% ethyl acetate/hexane to afford 097 g (35%) of the title compound.
