To a solution of tert-butyl[3-(6-methyl-5-nitropyridin-3-yl)prop-2-yn-1-yl]carbamate (2.98 g, 10.2 mmol) in MeOH (100 mL) was added palladium hydroxide on carbon (0.72 g). The reaction vessel was flushed with H2 and then the reaction mixture was allowed to stir at rt under an atmosphere of hydrogen overnight. The reaction mixture was filtered over a pad of Celite® and the filtrate was concentrated to give tert-butyl[3-(5-amino-6-methylpyridin-3-yl)propyl]carbamate (2.97 g, >99%) as a yellow oil. LCMS (FA): Rt=0.85 min, m/z=266.0 (M+H).
