Reaktionsschritte

4-Phenylpiperidine (0.5 g), p-fluorobenzonitrile (0.37 g) and potassium carbonate (0.78 g) are dissolved in N-methylpiperidone (5 ml), and the mixture is stirred at 1 20° C. for five hours. To the reaction solution is added ethyl acetate (50 ml), and the mixture is washed with water, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. To the resulting residue is added methanol, and the insoluble crystals are collected by filtration, dried under reduced pressure to give 4-phenyl-1-(4-cyanophenyl)-piperidine (0.39 g) as white needles.
