Carbon tetrabromide → HCID 10858994, compound

Participants

Reaction Steps

To a mixture of 1-(4-isobutylphenyl)pentanol and carbon tetrabromide in tetrahydrofuran was added triphenylphosphine and the mixture was stirred at room temperature for 1 hour. Insoluble materials were removed by filtration and the filtrate was concentrated. Hexane was added to the residue and the mixture was filtered again. Concentration of the filtrate gave crude 1-bromo-1-(4-isobutylphenyl)pentane. Sodium was added portionwise to 1,3-propanediol at 80° C. while stirring. The obtained crude 1-bromo-1-(4-isobutylphenyl)pentane was added thereto, and the mixture was stirred at 120° C. for 30 minutes. After the mixture was cooled, diluted hydrochloric acid was added thereto, and the mixture was extracted with ethyl acetate.
