Reaction Steps

2-[2-(2,4-Dichlorobenzyloxy)phenyl]-1-propene (1.0 g, 3.41 mmole), N-bromosuccinimide (0.61 g, 3.41 mmole) and azobisisobutyronitrile (2.8 mg, 0.017 mmole) were suspended in carbon tetrachloride (4 ml) and the suspension was refluxed with stirring for 12 hours. Then, the mixture was poured into water (30 ml) and extracted with ethyl acetate (50 ml). The extract was washed with water (50 ml) and dried over anhydrous soidum sulfate. After distilling off the solvent under reduced pressure, the residue was subjected to chromatography on a silica gel column and eluted with n-hexane to obtain the title compound (0.52 g, 41.0%). 1H-NMR (CDCl3, δ): 4.50 (s, 2H, CH2Br), 5.20 (s, 2H, ##STR49## 5.33 (d, 1H, =CH), 5.57 (d, 1H, =CH), 6.80-7.57 (m, 7H, aromatic).
