Procedure

Potassium hydroxide (10 g) was added to a solution of 3aminoquinuclidine dihydrochloride (10.45 g, 0.052 mole) in water (80 ml) saturated with sodium chloride. After stirring for 30 minutes, methylene chloride (75 ml) was added and the layers separated. The aqueous layer was washed with methylene chloride (2×75 ml), and the extracts combined with the methylene chloride layer above; dried over sodium sulfate, filtered, and the volume reduced to 100 ml. A solution of chloroacetyl chloride (3.11 g, 0.0273 mole) in methylene chloride (25 ml) was added dropwise and the mixture stirred overnight. The solvent was removed on a rotary evaporator. The residue was recrystallized from methanol-ethyl acetate to give a white solid (4.7 g), m.p. ca. 189°-195° C. The structure was confirmed by NMR.
