Versuchsvorschrift
According to GP, 2.22 mmol (=0.40 g) of 1-(4-fluorophenyl)piperazine and 2.22 mmol (=0.31 g=0.28 ml) of 4-chlorostyrene are reacted with 5 mol % (=0.111 mmol=70 μl) of n-BuLi solution. Column-chromatographic separation with ethyl acetatein-hexane gives the product 1-(4-fluorophenyl)-4-[2-(4-chlorophenyl)-1-ethyl]piperazine as a light-yellow solid.
