Procedure

To 6.2 g (46.5 mmol) of aluminum trichloride suspended in 50 ml of dichloroethane were added 3.02 g (30.2 retool) of succinic anhydride and 4.0 g (23.2 mmol) of 2-fluorobiphenyl were added thereto and the mixture was stirred at room temperature for 4 hours. The reaction solution was poured into hydrochloric acid containing ice, and extracted with chloroform. The organic layer was washed with water and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and then recrystallized from chloroform to obtain 5.6 g (89% yield) of the desired compound.
