1,1'-Biphenyl, 4-(1,1-dimethylethyl)-4'-nitro- → 4'-(1,1-Dimethylethyl)[1,1'-biphenyl]-4-amine

Participants

Reaction Steps

To a solution of the 4′-tert-Butyl-4-nitro-biphenyl (1.8 g) in ethanol (20 mL) is added palladium (10%) on carbon (0.15 g). The reaction is charged to 30 psi under a hydrogen atmosphere and allowed to stir for 4 h. The mixture is then filtered through a pad of Celite®. The solution is concentrated and purified by reverse phase HPLC using 0.1% TFA in water and acetonitrile to afford 1.6 g of the titled compound as a white solid. 1H-NMR.
