(2S,4S)-1-[[N-(4-Carboxybicyclo[2.2.2]oct-1-yl)amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile (50.0 mg), 5-bromo-1-pentanol (18.7 μL), potassium carbonate (23.5 mg), and N,N-dimethylformamide (1.5 mL) were mixed together. The mixture was stirred at room temperature for 4 hours. The insoluble materials in the mixture was filtered and the filtrate was concentrated under reduced pressure. The resulting residue was purified by a silica gel column (eluant:chloroform:methanol=10:1) to give (2S,4S)-4-fluoro-1-[[N-(5-hydroxypentyloxycarbonylbicyclo[2.2.2]oct-1-yl)amino]acetyl]pyrrolidine-2-carbonitrile (32.4 mg).
