Vorschrift

Four point three grams (32 mmol) of aluminum chloride was placed into 30 milliliter of 1,2-dichloroethane and a solution made by dissolving 2.0 g (25 mmol) of acetyl chloride, subsequently 5.0 g (21 mmol) of 4-bromo biphenyl into 20 milliliter of 1,2-dichloroethane was added while cooling with ice. The mixed solution was stirred as it is while cooling with ice for 4 hours. After completion of the reaction, adding water and an extraction was carried out using dichloro-methane. Further, washing with water, dried with the use of sodium sulfate. Removing the solvent by distillation, 5.9 g of crude 1-(4′-bromo-biphenyl-4-yl)-ethanone was obtained.
