実験手順

1-[1,1-Dimethylethoxycarbonyl]-4-(2-nitrophenyl)piperazine (PREPARATION 12, 7.61 g) is dissolved in ethanol (150 ml). Palladium on carbon (10%, 0.75 g) is added and the reaction is hydrogenated at 45 psi for 6 hr. The mixture is filtered thru celite and concentrated under reduced pressure to give the title compound.
