Procedure

A mixture of methyl 6-[(1-benzyl-4-piperidyl)amino]nicotinate (4.2 g) in MeOH (50 ml) was hydrogenated over 10% palladium-carbon (1.5 g) under an atmospheric pressure of hydrogen at ambient temperature under stirring for 15 hours. After removal of the catalyst and solvent was evaporated in vacuo and the residue was triturated with AcOEt and IPE. The precipitate was collected by filtration to give methyl 6-(4-piperidylamino)nicotinate (1.77 g).
