Reaction Steps

0.94 Gram (3.6 mmol) of triphenylphosphine and 1.49 g (4.5 mmol) of carbon tetrabromide were added to a solution prepared by dissolving 0.54 g (3 mmol) of 1-methyl-2-(3,5-dimethylphenoxy)ethanol in 10 ml of methylene chloride, and the resultant mixture was stirred at room temperature for 30 minutes. After the reaction, the solid was separated by filtration, and the remaining methylene chloride solution was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=5:1 (v/v)) to give 0.54 g of 1-(3,5-dimethylphenoxy)-2-bromopropane (yield 74.7%).
