실험 절차

95 mg (0.69 mmol) of potassium carbonate are added to a solution of 200 mg (0.69 mmol) of ethyl [(1-phenylaminocyclohexylmethyl)amino]-acetate and 55 μl (0.69 mmol) of chloroacetyl chloride in 15 ml of dimethylformamide. The reaction medium is stirred at reflux for 6 h and poured into water and extracted with ethyl acetate. The organic phases are collected and washed with water. They are dried over sodium sulfate. The solvents are evaporated. 220 mg of ethyl (3-oxo-1-phenyl-1,4-diazaspiro[5.5]undec-4-yl)acetate are obtained in the form of an orange oil. Yield=97%.
