Reaction Steps
A solution of benzyl 4-(6-oxo-6,7-dihydro-5H-imidazo[4,5-c]pyridazin-5-yl)piperidine-1-carboxylate (35 mg, 0.099 mmol) and 10% Pd/C (50 mg) in EtOH (5 mL), was hydrogenated under a balloon overnight. The reaction was filtered through Celite with more EtOH and concentrated to afford the title compound (26 mg). MS 220.2 (M+1).
