合成路线1
该中间体在本合成路线中的序号：(IV)The alkylation of 2-(3,4-dimethoxyphenyl)ethylamine (I) with 2-bromoethanol (II) provides the bis(hydroxyethyl) amine (III). Subsequent chlorination of diol (III) with SOCl2 affords the corresponding bis(chloroethyl) amine (IV). This is finally cyclized with 3-phenylpropylamine (V) to furnish the title piperazine derivative, which is isolated as the dihydrochloride salt.
