4-(Aminomethyl)piperidine (I) was protected as the benzylideneimine (III) by condensation with benzaldehyde (II). Further acylation of (III) at the secondary amino group by treatment with di-tert--butyl dicarbonate gave, after acid hydrolysis of the imine, the N-Boc-piperidine (IV). The benzoic acid derivative (V) was activated as the mixed anhydride by treatment with ethyl chloroformate and triethylamine, and subsequently condensed with amine (IV) to provide the corresponding amide (VI). Then, the N-tert-butoxycarbonyl group was eliminated with HCl to give the piperidine (VII), which was finally alkylated with halide (VIII) in the presence of K2CO3 in DMF to furnish the title compound.
