Reaction Steps
9.6 ml of thionyl chloride are added dropwise into a 250 ml round-bottomed flask containing 60 ml of n-octanol cooled to 0° C. After stirring for 10 min at 0° C., 18.6 g of (3S)-2-azabicyclo[2.2.2]octane-3-carboxylic acid (described in Patent FR 2,585,709) are added slowly. The reaction mixture is left stirring overnight at room temperature, then heated for 6 hours at 80° C. and again left overnight at room temperature. After adding 100 ml of anhydrous ether and filtering off the unreacted hydrochloride, the filtrate is condensed and then taken up with a water/ether mixture (50:50). The expected product is obtained after concentration of the aqueous phase and then drying under vacuum.
