Three grams of said 3-fluoro-4-methoxybiphenyl was dissolved in 14 ml of carbon disulfide, and 1.17 g of acetyl chloride and 2.36 g of aluminum chloride were added, followed by stirring the mixture for 10 hours. Twenty milliliters of 10% hydrochloric acid and then 5 ml of water were added, and the precipitate was filtered and washed with water. The resulting crude crystals were recrystallized from ethanol to obtain 2.75 g of 3'-fluoro-4'-methoxy-4-acetylbiphenyl (yield 76%).
