실험 절차

To a solution of tert-butyl (1R,3S,4S,6R)-3-{[(2S)-2-cyano-1-pyrrolidinyl]carbonyl}-6-hydroxy-2-azabicyclo[2.2.1]heptane-2-carboxylate obtained in Example 5-7 (209 mg) in dimethylformamide (2.5ml), were added 2-fluoropyridine (109 mg) and sodium hydride (60% in mineral oil, 25 mg). The mixture was then stirred at room temperature for 50 minutes. The reaction mixture was diluted with ethyl acetate, and washed successively with water and brine. The organic phase was dried over sodium sulfate and evaporated in vacuo. The residue was chromatographed on silica gel eluting with ethyl acetate to give the target compound (162 mg).
