実験手順

To a solution of tert-butyl 4-(3-nitrophenyl)piperazine-1-carboxylate in EtOH (20 mL) and THF (10 mL) was added Pd/C (500 mg), the mixture was charged with H2 (1 atm) and stirred for 16 h. Pd/C was filtered off, the filtrate was concentrated to give tert-butyl 4-(3-aminophenyl)piperazine-1-carboxylate (1.71 g).
