실험 절차

To a suspension of anhydrous aluminum chloride (19.5 g) dispersed in m-xylene (150 ml) was added dropwise 4-fluorobenzoyl chloride (21.1 g) under ice-cooling. The mixture was stirred at 0-10° C. for 3 hr and poured into 6N hydrochloric acid. The reaction mixture was partitioned and the obtained organic layer was washed successively with water, 10% aqueous sodium hydroxide solution and water. The solvent was evaporated to give a 96:4 mixture (30.2 g, 99%) of 1,3-dimethyl-4-(4′-fluorobenzoyl)benzene and 1,3-dimethyl-2-(4′-fluorobenzoyl)benzene as pale-yellow oil. 1,3-Dimethyl-4-(4′-fluorobenzoyl)benzene
