Reaction Steps

1-Methyl-4-piperidin-3-yl-piperazine (1.46 g, 7.96 mmol), 4-Fluoronitrobenzene (1.0 g, 7.2 mmol) and Potassium carbonate (2.50 g, 18.1 mmol) were dissolved in N,N-Dimethylformamide (50 mL, 600 mmol). The reaction mixture was then heated at 100° C. and was allowed to stir overnight. The reaction mixture was poured over saturated ammonium chloride and organics were extracted with dichloromethane/ethyl acetate. Combined extracts were then dried over sodium sulfate, filtered and reduced. The crude reaction mixture was then purified by Isco flash column chromatography (hexanes/ethyl acetate eluent). Combined fractions were reduced and dried under vacuum to afford 1.40 g of 1-Methyl-4-[1-(4-nitro-phenyl)-piperidin-3-yl]-piperazine.
