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-monohydrateand crystalline (S)-3-aminopiperidine-dihydrochloride-monohydrate.

Alkylnitrites were prepared in good to excellent yields by treatment of alcohols and thiols with triphenylphosphine/2,3-dichloro-5,6-dicyanobenzoquinone/Bu 4 NNO 2 in acetonitrile. This method is highly selective for the conversion of primary alcohols to alkylnitrites in the presence of secondary and tertiary alcohols and thiols.
