Versuchsvorschrift
To a stirred solution of 1-(4-ethyl-3-fluoro-phenyl)-ethanone (166 mg, 1 mmol) in 1,4-dioxane (5 mL), bromine was added dropwise at room temperature. After the addition, the solvent was removed and the residue was chromatographed (dichloromethane/hexanes) to give a solid. 77 mg, 31%. 1H NMR(CDCl3, 300MHz), σ 1.22 (t, 3H), 2.73 (q, 2H), 4.40 (s, 2H), 7.735 (t, 1H), 7.56-7.75 (dd, 2H).
