Reaktionsschritte

First, 23.6 g of anhydrous aluminum chloride and 120 ml of methylene chloride were put in a 300 ml flask. After 14.0 g of acetyl chloride was dropped into the mixture at 5° C. or less, the resultant mixture was stirred keeping the same temperature for 30 minutes. Then, 45.2 g of 4-(trans-4-pentylcyclohexyl)biphenyl was added to resultant mixture at 5° C. or less and stirred for 30 minutes at room temperature. After the reaction, the reaction solution was poured into dilute hydrochloric acid, and an organic layer was separated. The organic layer was then washed with water and dried with sodium sulfate. The solvent was then distilled off. The residue was recrystallized from acetone to obtain 24.0 g (Y: 46.0%) of 4-acetyl-4′-(trans-4-pentylcyclohexyl)biphenyl. The purity of the resultant compound was 99.7% as measured by GC.
