A process for preparing a 1-aryl-4-(arylethyl)piperazine of the formula (I)
by reacting a 1-arylpiperazine of the formula (II)
with an aromatic olefin of the formula (III)
Ar′CR1═CHR2 (III)
in an inert solvent in the presence of at least one basic catalyst, where in the formulae (I) to (III)
Ar and Ar′ independently of one another are an aryl radical, selected from the group of the fused and unfused C6-C22-aromatics and the fused or unfused C5-C22-heteroaromatics which have at least one nitrogen, oxygen or sulfur atom in the ring; and
R1 and R2 independently of one another are a hydrogen atom, a C1-C8-alkyl radical or an aryl radical Ar.
一种制备式(I)的1-芳基-4-(芳基乙基)
哌嗪的方法,通过在惰性溶剂中,在至少一个碱性催化剂的存在下,将式(II)的1-芳基
哌嗪与式(III)的芳香烯烃Ar′CR1═CHR2反应而得,其中在式(I)到(III)中,Ar和Ar′分别是取自融合和未融合的C6-C22芳香族和至少有一个氮、氧或
硫原子在环中的融合或未融合的C5-C22杂环芳香族的芳基基团;而R1和R2分别是氢原子,C1-C8烷基基团或芳基基团Ar。
