Reaction Steps

1-(4-methoxyphenyl)piperazine was dissolved in N,N-dimethylformamide, and potassium carbonate and 1-bromo-2-chloroethane were added. The resulting mixture was stirred at room temperature overnight, the solid material filtered off, and the solvent removed from the filtrate under reduced pressure. The residue was purified by biotage chromatography eluting with 3:7 ethyl acetate:hexanes, to provide 1-[4-(2-chloroethyl)piperazinyl]-4-methoxybenzene.
