Palladium on carbon (10 wt %, 0.100 g) was added to a solution tert-butyl 4-(1H-imidazol-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (0.300 g, 1.20 mmol) in ethanol (20 mL), and the mixture stirred under a hydrogen atmosphere at room temperature for 2 h. The reaction mixture was filtered, and the filtrate was concentrated under vacuum to afford tert-butyl 4-(1H-imidazol-2-yl)piperidine-1-carboxylate (0.300 g, 99%) as an off-white solid. MS (ESI, pos. ion) m/z 252 [M+H]+.
