Aniline → 1-Anilino-3-{4-[4,4-bis(4-fluorophenyl)butyl]piperazin-1-yl}propan-2-ol

Participants

Reaction Steps

3.86 g (0.01 mol) of 1-[4,4-bis(4-fluorophenyl)butyl]-4-(2,3-epoxypropyl)piperazine and 0.93 g (0.01 mol) of aniline were refluxed with heating with 200 ml of DMF for 21 hours in the presence of a catalytic amount of an alkali such as potassium carbonate. DMF was distilled off under reduced pressure, and a residue was extracted with ethyl acetate. After washing with water and drying, the ethyl acetate was distilled off under reduced pressure to obtain 5 g of a crude subject compound of a viscous liquid. The obtained compound was refined by flush chromatography and fractional thin-layer chromatography with solvent mixtures of ethyl acetate--methanol and methylene chloride --methanol respectively to obtain 0.5 g of the subject compound in a viscous liquid state.
