tert-Butyl 4-{[2-(2-nitrophenyl)ethyl]amino}piperidine-1-carboxylate → Tert-butyl 4-{[2-(2-aminophenyl)ethyl]amino}piperidine-1-carboxylate

Participants

Reaction Steps

To a solution of tert-butyl 4-(2-nitrophenethylamino)piperidine-1-carboxylate (10.5 g) in EtOH (180 ml) was added 10% Pd/C (1.05 g) and the reaction mixture was stirred at RT under an atmosphere of H2 overnight. The reaction mixture was filtered and the resulting solution was evaporated to dryness giving the desired product (9.6 g). LC/MS (10% to 99%): M/Z (M+H)+ (obs)=320; tR=2.06.
