Procedure
A solution of 2-(3-furan-2-yl-phenyl)ethanol and carbon tetrabromide in DCM was treated with triphenylphosphine at 0° C. The resultant mixture was stirred at room temperature for one hr. The volatiles were removed under reduced pressure. Purification by column chromatography (5% ethyl acetate/hexanes) gave 3-(2-furyl)phenethyl bromide. 1H NMR (CDCl3) δ 7.57 (d, J=1.6, 1H), 7.55 (s, 1H), 7.47 (s, 1H), 7.33 (t, J=8.0 Hz, 1H), 7.11 (d, J=8.0 Hz, 1H), 6.66 (m, 1H), 6.47 (m, 1H), 3.60 (t, J=7.2 Hz, 2H), 3.20 (t, J=7.2 Hz, 2H).
