Reaction Steps

N,N-Bis(2-chloroethyl)-4-methylbenzenesulfonamide (4.0 g, 13.50 mmol) and (R)-1-(4-bromophenyl)ethanamine (2.57 g, 12.83 mmol) in DIPEA (5 mL) were stirred and heated at 125° C. for 32 hours. The resulting dark mixture was cooled to 80° C. then a mixture of EtOH/water (70/30, 20 mL) added slowly to give a brown precipitate. The precipitate was collected by filtration, washed with EtOH/water (70/30) and iso-hexane and air dried to afford (R)-1-[1-(4-bromophenyl)ethyl]-4-tosylpiperazine (4.45 g, 78%) as a brown solid, which was used without further purification.
