実験手順

0.36 g of sodium hydride is added to a solution of 2.46 g of 1-(4-nitrophenyl)-3-azabicyclo[3.1.1]heptane-2,4-dione in 25 ml of N,N-dimethylformamide and the whole is stirred at room temperature for 30 minutes. 2.68g of n-heptyl bromide dissolved in 10 ml of N,N-dimethylformamide are then added dropwise thereto. When the reaction is complete, the reaction mixture is freed of N,N-dimethylformamide. The residue is partitioned between ethyl acetate and water, and the organic phase is dried over magnesium sulphate. After concentration by evaporation and purification by chromatography over silica gel in the system ethyl acetate/hexane 2:5, the product is obtained in the form of a solid. Melting point 91°-92°. Rf (ethyl acetate/hexane 4:1)=0.63.
