Procedure
A solution of 147 g (1.05 moles) of 4-nitrobenzoyl chloride in 250 ml of 1,2-dichloroethane and a solution of 154 g (1.0 mole) of biphenyl in 200 ml of 1,2-dichloroethane are added dropwise, in succession, to the suspension of 160 g (1.2 moles) of anhydrous aluminum chloride in 400 ml of 1,2-dichloroethane at 0° C. The mixture is allowed to reach room temperature, after which it is stirred for 2 hours at 50° C. and poured carefully onto ice water. The precipitate is filtered off under suction, washed thoroughly with water and recrystallized from ethanol to give 230 g (89% of theory) of brown crystals of melting point 174°-176° C.
