実験手順
Bromine (1.47 mL, 28.69 mmol) in acetic acid (50 mL) was added dropwise over a 30 minutes period into a cold (5° C.) mixture of 4′-(2-benzyl-benzo[b]thiophen-3-yl)-biphenyl-4-ol (7.5 g, 19.13 mmol), potassium acetate (18.6 g, 190.13 mmol), and acetic acid (200 mL). After the addition the mixture was poured into water, and extracted with ethyl ether. The organic extracts were washed with aqueous sodium bisulfite and dried over MgSO4. Evaporation and purification by flash chromatography on silica gel (hexanes/EtAOc/CH2Cl2 3:1:1) gave 4′-(2-benzyl-benzo[b]thiophen-3-yl)-3-bromo-biphenyl-4-ol as a light yellow solid (2.4 g): mp 54-56° C. MS m/e 477 (M+);
