実験手順
Ethyl bromoacetate (3.7 g, 18.4 mmol, Aldrich) was added in portions to a solution of homopiperazine (2.76 g, 27.6 mmol, Avocado) in N,N-dimethylformamide (15 mL) at room temperature over 1.5 h. The mixture was then stirred for additional 4 h followed by an aqueous workup. The crude was purified by column flash chromatography to give homopiperazine-acetic acid ethyl ester (471 mg).
