실험 절차

5-benzyl-5-azaspiro[2.4]heptan-7-one (300 mg) was mixed with hydrazine (600 mg) and NaOH (300 mg) in H2O (2 ml). The mixture was refluxed for overnight and purified by column chromatography to give 5-benzyl-5-azaspiro[2.4]heptane that was hydrogenated at 50 psi with Pd—C (10%, 80 mg) in EtOH (15 ml) for overnight followed by filtration through Celite to give 5-azaspiro[2.4]heptane. This product was mixed with 2-Bromoethanol and K2CO3 in Acetonitrile. The reaction was refluxed overnight and filtered, the filtrate was evaporated and purified on silica gel column to give the titled product. Mass: (M+1), 142
