A clear solution of tert-butyl((5-cyano-6-methoxy-4-methylpyridin-2-yl)methyl)carbamate (0.65 g, 2.344 mmol) in HOAc (5 mL) and Ethanol (20 mL) was treated on an H-Cube apparatus (50 psi, 40° C., 1 mL/min., Raney Nickel cartridge) for 18 hr overnight. LCMS showed that the reaction was complete. The reaction was evaporated to dryness under vacuum. Purified by silica gel chromatography (Analogix, SF25-60 g, 0 to 10% (5% NH4OH/MeOH) in CH2Cl2). The pure fractions were combined and evaporated to dryness under vacuum to give the product tert-butyl((5-(aminomethyl)-6-methoxy-4-methylpyridin-2-yl)methyl)carbamate (0.58 g, 2.061 mmol, 88% yield) as a clear thick oil.
