Reaction Steps

Ethyl 4-(piperazin-1-yl)benzoate (1.5 g), 1-(bromomethyl)-2-nitrobenzene (1.383 g) and sodium carbonate (2.036 g) were suspended in anhydrous N,N-dimethylformamide (20 mL) at room temperature for 4 hours. The reaction mixture was diluted with ethyl acetate, washed with water and brine, and concentrated. The residue was purified by flash column purification with 10-40% ethyl acetate/hexane to afford the title compound.
