Procedure

4-(Benzyl-methyl-amino)-piperidine-1-carboxylic acid tert-butyl ester was dissolved in DCM and methanol and 2.0M HCl in ether was added. After 3 hours the solvent was removed in vacuo and the residue was recrystallised from ethyl acetate/methanol to yield benzyl-methyl-piperidin-4-yl-amine (hydrochloride salt).
