Carbon tetrabromide → 2-(Bromomethyl)-5,8-dioxaspiro[3.4]octane

Participants

Reaction Steps

Triphenylphosphine (6.28 gm, 24 mmol) in dichloromethane was added drop wise to a solution of 5,8-dioxaspiro[3.4]oct-2-ylmethanol (2.3 gm, 16 mmol) (step d) and tetrabromomethane (6.62 gm, 20 mmol) in dichloromethane. The reaction mixture was stirred at room temperature for about 6 hours. The solvent was removed under reduced pressure and the residue was extracted with diethyl ether. The organic layer was concentrated under reduced pressure to get a crude product, which was purified by column chromatography.
