Reaction Steps

To a stirred solution of 1-(5-bromo-pentyloxy)-3-nitro-benzene (432 mg, 1.5 mmol) and 1-(4-fluoro-phenyl)-piperazine (297 mg, 1.65 mmol) in acetonitrile (5 mL) was added potassium carbonate (414 mg, 3.0 mmol). After refluxed for 6 hours, the reaction mixture was quenched with water (10 mL) followed by extraction with ethyl acetate (10 mL×3). The combined organic layers were washed with brine and then concentrated under vacuum. The resulting residue was purified by silica gel column chromatography to give 1-(4-fluoro-phenyl)-4-[5-(3-nitro-phenoxy)-pentyl]-piperazine (549 mg, 1.42 mmol, 94%) as a yellow solid.
