Versuchsvorschrift

A solution of dimethyl itaconate (0.5 g, 3.16 mmoles), cycloheptylamine (0.357 g, 3.16 mmoles) in methanol (5 mL) was heated at 85° C. for eighteen hours. The solvent was evaporated in vacuo and the resulting crude product was purified by flash chromatography (hexanes/ethyl acetate 80:20 to 20:80) to give the title compound as a colorless oil.
