참여 물질

반응 단계

1-Acetylpiperazine (1.28 g, 10 mmoles), 1,2-dichloroethane (5 g, 50 mmoles), anhydrous sodium carbonate (2.5 g) and potassium iodide (25 mg) are combined in 40 ml of 3-methyl-2-butanone and refluxed for 16 hours. The reaction mixture is evaporated to dryness in vacuo and the residue distributed between 100 ml of water and 150 ml of methylene chloride.
