Reaction Steps

The 1-benzyl-4-(5-nitropyridin-2-yl)piperazin-2-one (B-14) (195 mg, 0.63 mmol) was stirred in EtOAc (30 mL) and MeOH (15 mL). The mixture was treated with PtO2 (72 mg) and stirred at RT under 1 atm of H2 for 1 h 10 min. Then, the reaction mixture was filtered over a pad of celite and concentrated to yield 4-(5-aminopyridin-2-yl)-1-benzyl-piperazin-2-one (B-15) (176 mg, 100% yield). MS (M+1): 283.2
