실험 절차

To a solution of 1-acetyl-4-[3-(methyloxy)-4-nitrophenyl]piperazine (0.4 g, 1.43 mmol) in ethanol: ethyl acetate (5:1) was added 10% Pd/carbon (˜0.100 g, Lancaster) and the mixture was rapidly stirred under 50 psi H2 overnight. The catalyst was removed by vacuum filtration through a celite pad, rinsed with methanol, and concentrated by rotary evaporation to give 4-(4-acetyl-1-piperazinyl)-2-(methyloxy)aniline (0.3 g, 84%). ESIMS (M+H)+=250.
