Procedure

To a solution of (1S,3S,4S,5R)-2-(tert-butoxycarbonyl)-5-hydroxy-2-azabicyclo[2.2.2]octane-3-carboxylic acid obtained in Example 2-5 (4.05 g), (2S)-2-pyrrolidinecarboxamide (1.77 g) and 1-hydroxybenzotriazole hydrate (1.68 g), were added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (3.15 g) and N,N-diisopropylethylamine (5.2 mL) with cooling on an ice bath. After 5 minutes, the ice bath was removed and the mixture was stirred overnight at room temperature.
