실험 절차

80 mg (0.57 mmol) of potassium carbonate are added to a solution of 120 mg (0.52 mmol) of 1-phenyl-1,3-diazaspiro[4.4]nonane-2,4-dione and 145 mg (0.57 mmol) of 2-chloro-N-(2,6-diisopropylphenyl)acetamide in 20 ml of dimethylformamide. The reaction medium is stirred at room temperature for 24 hours. It is then poured into water and extracted with ethyl acetate. The organic phases are collected, washed with water and dried over sodium sulfate. The solvents are evaporated. The residue is chromatographed on silica gel (heptane and then heptane/ethyl acetate 80/20, v/v). 120 mg of N-(2,6-diisopropylphenyl)-2-(2,4-dioxo-1-phenyl-1,3-diazaspiro[4.4]non-3-yl)acetamide are obtained in the form of a white solid. Yield=51%, m.p.=275-7° C.
