Ethanol → 4-[3-(4-Methylpiperazin-1-yl)propoxy]aniline

Participants

Reaction Steps

Into a Round bottom flask, 1-Methyl-4-[3-(4-nitro-phenoxy)-propyl]-piperazine (4.10 g, 0.0147 mol), 10% Pd/C (10:90, Palladium:carbon black, 1.6 g, 0.0015 mol), and Ethanol (100 mL, 2 mol) were added. The mixture was evacuated under house vacuum and charged with a hydrogen balloon (3×). The reaction was stirred at room temperature under an atmosphere of Hydrogen via a balloon. The solid was filtered. The solvent was removed under vacuum to give 4-[3-(4-Methyl-piperazin-1-yl)-propoxy]-phenylamine a white solid (2.86, 78%). 1H (DSMO-d6)-6.62 (dd, 1H, J=2.08, 4.57 Hz), 6.49 (dd, 2H, J=2.16, 5.64 Hz), 4.56 (bs, 2H), 3.82 (t, 2H, J=6.40 Hz), 2.20-2.45 (m, 10H), 2.13 (s, 3H), 1.70-1.83 (m, 2H)
