Procedure

To a solution of 1′,3′,3′,6-tetramethyl-5-nitro-1′,2′,3′,6′-tetrahydro-3,4′-bipyridine (0.912 g, 3.49 mmol) in MeOH (70 mL) was added palladium hydroxide (20 wt. % Pd (dry basis) on carbon, 808 mg). The reaction mixture was flushed with hydrogen gas and allowed to stir at rt overnight under an atmosphere of hydrogen. The reaction mixture was filtered through a Celite® pad and washed with MeOH. The filtrate was concentrated to give 2-methyl-5-(1,3,3-trimethylpiperidin-4-yl)pyridine-3-amine (0.814 g, 100%). LCMS (FA): Rt=0.24 min, m/z=234.4 (M+H).
