Abstract

Procedure for the preparation of aminopiperidine derivatives, of formula: **(See formula)** wherein each of R1, R2 and R3 are hydrogen or lower alkoxy, which can be independently exchanged, and the substituted benzamide radical is attached to positions 2, 3 or 4 of the piperidine nucleus, and R'1 and R' 2 are hydrogen or an amino radical and at least one of R'1 and R'2 represents an amino radical, characterized in that it comprises hydrogenating the compound of formula: **(See formula)** wherein R1, R2, R3 and the position of the substituted benzamide radical are defined as above and R''1 and R''2 represent hydrogen or a nitro radical and at least one of R''1 and r'' 2 means the nitro radical.
