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.

The present invention provides a compound of formula (I), or a pharmaceutically acceptable salt or solvate thereof, wherein: Y is selected from C or N; X is selected from O or S; R1 is selected from hydrogen or methyl; Z is CR2R3, wherein R2 and R3 are each independently selected from hydrogen and (1-5C)alkyl, or R2 and R3 are taken together with the carbon atom to which they are attached to form a cyclopropyl or cyclobutyl ring; Z1 is selected from CR4R5, O, S, C(O) or NR6, wherein R4 and R5 are each independently selected from hydrogen, OH, (1-5C)alkyl and phenyl, or R4 and R5 are taken together with the carbon atom to which they are attached to form a cyclopropyl ring, and R6 is selected from hydrogen and (1-5C)alkyl, provided that one, but not both, of Z and Z1 is CH2.
