合成路线图解说明:

The condensation of 5,6-dimethoxy-1-indanone (I) with 1-benzylpiperidine-4-carboxaldehyde (II) by means of butyllithium and diisopropylamine in THF gives 1-benzyl-4-(5,6-dimethoxy-1-oxoindan-2-ylidenemethyl)piperidine (III), which is reduced with H2 over Pd/C in THF and treated with HCl in dichloromethane - ethyl acetate.
