Processes for preparing an amine compound by catalytically hydrogenating a precursor nitrile compound. In a particular aspect, the present hydrogenation process occurs in a dipolar organic solvent in the presence of a palladium/carbon catalyst and a strong anhydrous protic acid. In a further aspect, the preferred embodiment relates to a process for deprotecting a compound to produce an amine compound. In yet a further aspect, the preferred embodiment relates to amine products produced by the present processes. These amine products may be used for a variety of purposes.
