実験手順
According to GP, 2.22 mmol (=0.43 g) of 1-(2-methoxyphenyl)piperazine and 2.22 mmol (=0.23 g=0.25 ml) of styrene are reacted with 5 mol % (=0.111 mmol=70 μl) of n-BuLi solution. Column-chromatographic separation with ethyl acetate/n-hexane (1:2) gives the product 1-(2-methoxyphenyl)-4-(2-phenyl-1-ethyl)piperazine as a yellow oil.
