Carbon tetrabromide → HCID 21476913, compound

Participants

Reaction Steps

To a magnetically stirred solution of 0.405 g (1.94 mmol) of the product of Step D dissolved in 5.0 mL of methylene chloride was added 0.638 g (2.43 mmol) of triphenylphosphine followed by 0.806 g (2.43 mmol) of carbon tetrabromide at room temperature. The reaction mixture was stirred for 30 minutes at room temperature, then the magnetic stir bar was removed and the methylene chloride was evaporated in vacuo. The residue was purified on a silica gel flash chromatography column eluted with 10% EtOAc-hexane, and evaporation of the purified fractions and solvent removal in vacuo afforded 0.496 g (94%) of the title compound.
