The present invention relates to a process for the preparation of enantiomerically enriched 3-aminopiperidine, and in particular of its R-enantiomer (R)-3-aminopiperidine. The invention also relates to an enantiomerically enriched intermediate of said process and to specific acid-addition salts of 3-aminopiperidine (hereinafter also APIP) that are useful for obtaining a single enantiomer of APIP, and to crystalline (R)-3-aminopiperidine-dihydrochloride-monohydrate and crystalline (S)-3-aminopiperidine-di-hydrochloride-monohydrate.
