Procedure
A mixture of 5.0 g (0.029 mol) of 3-bromophenol, 29 ml (0.29 mol) of 1,3-dibromopropane and 12 g (0.087 mol) of potassium carbonate in 75 ml ofacetone was stirred ar reflux for 22 hours. The reaction mixture was filtered and the filtrate was concentrated at reduced pressure. The residue was purified by HPLC using 3% ethyl acetate-hexane to give 4.9 g (58% yield) of 3-(3-bromopropoxy)bromobenzene. The structure was confirmedby the nmr spectrum.
