Reaction Steps

35.1 g of 1-benzyl-4-[2,2-bis(4-fluorophenyl)ethyl]-piperazine hydrochloride were hydrogenated in 1,400 ml of methanol on 8 g of palladium-on-charcoal (10%) at room temperature for 1 hour. The catalyst was filtered off with suction, the solvent was evaporated off, the residue was dissolved in 200 ml of water, the pH was brought to 10 with 2N NaOH, the solution was extracted several times with methylene chloride and the extracts were dried and concentrated.
