Versuchsvorschrift

To a round-bottom flask was added 4-(6-nitropyridin-3-yl)piperazin-2-one 141-3 (0.7 g, 3.1 mmol), Pd/C (0.2 g) and methanol (20 mL). The reaction was stirred for 4 hours under hydrogen atmosphere by attaching a hydrogen balloon. The reaction was flashed with nitrogen and the solid was removed by filtration. The solvent was removed by rotary evaporation to give 4-(6-aminopyridin-3-yl)piperazin-2-one 141-4 as purple solid. MS m/z 193.2 (M+1).
