Participants

Reaction Steps

1-(2,2-Dimethylpropyl)-5-nitro-1H-1,2,3-benzotriazole (4.46 g, 19.04 mmol, 1.0 equiv.) was dissolved in ethanol (50 ml), flushed with nitrogen, and charged with 10% Pd/C (2.026 g, 1.904 mmol, 0.1 equiv.). After sparging with nitrogen, the mixture was sparged with hydrogen (1 atm) and stirred at ambient temperature for 5 hours. The mixture was filtered through Celite, the residue was washed with methanol and the filtrate was concentrated in vacuo, providing the titled compound. LRMS m/z (M+H) 205.0 found, 205.3 required.
