Ethanol → 3-(4-Methylpiperazin-1-YL)-5-(trifluoromethyl)aniline

Participants

Reaction Steps

Into a 100 mL round bottom flask under inert atmosphere was placed 1-methyl-4-(3-nitro-5-(trifluoromethyl)phenyl)piperazine (0.736 g, 2.54 mmol), 10% palladium on carbon (90 mg), ethanol (40 mL), and acetic acid (20 mL). The atmosphere was exchanged with hydrogen gas via balloon. The reaction was allowed to stir 3 days at room temperature, then filtered through celite and concentrated under reduced pressure to afford the crude as an orange oil. The crude mixture was purified via silica column chromatography with a solvent solution of 90%/10%/1% ratio of CH2Cl2/CH3OH/NH4OH, to afford the title compound. MS m/z=260 [M+H]+; Calc'd for C12H16F3N3: 259.3.
