Reaction Steps

Piperazine (12.9 g) was dissolved in DMF (100 mL), and a solution of 2-fluoronitrobenzene (7.06 g) in DMF (30 mL) was added dropwise. The mixture was stirred at room temperature for 3 hr. The reaction mixture was added to water and the mixture was extracted with ethyl acetate. The extract was washed with water and dried. The solvent was evaporated to give 1-(2-nitrophenyl)piperazine (7.7 g) as a red oil.
