Reaction Steps

A mixture of 4-bromophenol (8.65 g), potassium iodide (83 mg), potassium carbonate (6.9 g) and propyl bromide (6.15 g) was heated under reflux in acetone (100 ml) for 48 hours. The reaction was cooled to ambient temperature, filtered and the acetone removed in vacuo to give an amber oil. This was purified by gradient elution with 20% ethyl acetate/isohexane through a silica gel Mega Bond Elut column to give 1-bromo-4-propoxybenzene (9.4 g) as a clear oil, mass spectrum (+ve CI): 214 (M+H)+.
