Procedure

According to GP, 2.22 mmol (=0.36 g=0.34 ml) of phenylpiperazine and 2.22 mmol (=0.26 g=0.30 ml) of 3-methylstyrene are reacted with 5 mol % (=0.111 mmol=70 μl) of n-BuLi solution. Column-chromatographic separation with ethyl acetate/n-hexane (3:1) gives the product 1-phenyl-4-[2-(3-methylphenyl)-1-ethyl]piperazine as a light-yellow solid.
