Participants

Reaction Steps

tert-Butyl 4-(6-nitro-1H-indazol-1-yl)piperidine-1-carboxylate (3.00 mmol, 1.04 g) and palladium (10% on C) (0.150 mmol, 0.160 g) in ethanol (30 mL) were stirred under a hydrogen atmosphere at 5 bar for 1 hour. The reaction mixture was filtered and concentrated at reduced pressure to afford the title compound (1.4 g). MS (ESI) m/z 317.2 [M+H]+
