A solution of N-bromosuccinimide (NBS) (48 g; 0.27 mol) dissolved in DMF (160 ml) was added dropwise to 3-dodecylthiophene (68 g; 0.27 mol) dissolved in DMF (110 ml). The reaction solution was stirred for one day, 750 ml of water was added thereto. An organic material was extracted from ethyl ether (3×300 ml), washed with brine and water, and then the residual moisture was removed over anhydrous magnesium sulfate. After removing the solvent, the residue was distilled off under reduced pressure at 125° C./˜5 mmHg to obtain a product (84.85 g, yield of 94%).
