실험 절차
To a solution (70 mL) of the crude 1-(1,2-diamino-1-methyl ethyl)-1-cyclopropanecarboxylic acid dihydrochloride (800 mg, 3.46 mmol) in acetonitrile was added 1,1,1,3,3,3-hexamethyldisilazane (7.38 mL, 34.6 mmol), and the mixture was heated under reflux in an oil bath at 100° C. for 4 hours under nitrogen atmosphere. The mixture was cooled to room temperature, and after adding methanol (70 mL), the solvent was removed by distillation under reduced pressure to obtain crude 7-amino-7-methyl-5-azaspiro[2.4]heptan-4-one as a pale brown gummy solid.
