Procedure
At room temperature, 0.31 g (2.2 mmol) of 2-(2-fluorophenyl)ethylamine and 0.22 g (2.2 mmol) of triethylamine in 10 ml of absolute toluene were admixed dropwise with a solution of 0.49 g (2.0 mmol) of 2-benzoylbenzoyl chloride in 10 ml of absolute toluene. The reaction mixture was heated under eflux for 3 h. After cooling, the turbid solution was admixed with 20 ml of water. The organic phase was separated off, diluted with 20 ml of toluene and washed three times with 1 M hydrochloric acid. To complete the extraction, the combined aqueous phases were extracted with diethyl ether. The combined organic phases were washed three times with 1 M aqueous sodium hydroxide solution and once with saturated sodium chloride solution, dried over sodium sulfate and evaporated to dryness using a rotary evaporator. The residue was recrystallized from toluene. The resulting colorless crystalline product was filtered off with suction and dried. Yield: 53 g. M.p.: 208° C.
