实验步骤: Ethyl 4-aminobicyclo[2.2.2]octane-1-carboxylate (115 mg) was dissolved in N,N-dimethylformamide (1.5 mL) and diisopropylethylamine (100 μL) was added to the solution. (2S)-1-(2-Bromoacetyl)pyrrolidine-2-carbonitrile (120 mg) in N,N-dimethylformamide (1 mL) was then added dropwise at room temperature. The mixture was stirred for 2 hours at room temperature and was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluant:chloroform:methanol=10:1) to give (2S)-1-[[N-(4-ethoxycarbonylbicyclo[2.2.2]oct-1-yl)amino]acetyl]pyrrolidine-2-carbonitrile (95.1 mg). was concentrated under reduced pressure The residue was purified by silica gel column chromatography (eluant:chloroform:methanol=10:1)
