实验步骤: Potassium-tert-butoxide (2.46 g) was added to a stirred, ice-cooled suspension of (4-butoxybenzyl)-triphenylphosphonium bromide (10.1 g) in dry tetrahydrofuran (300 ml) under an atmosphere of argon. The reaction mixture was stirred at room temperature for 1 hour. The reaction mixture was cooled to -10° C. and a solution of 3-formylquinuclidine (750 mg) in dry tetrahydrofuran (20 ml) was added dropwise over 15 minutes. The reaction mixture was stirred at room temperature overnight and water (1.0 ml) was then added. The tetrahydrofuran was evaporated and the residue was triturated several times with ether and filtered. The ether extracts were combined and evaporated to give an oil which was purified by flash column chromatography, using 10% methanol in dichloromethane containing 1% 0.880 ammonia as eluent, to give Z-3-[2-(4-butoxyphenyl)vinyl]-quinuclidine (Rf=0.3). This was dissolved in ether and an excess of a solution of hydrogen chloride in ether added to give a solid which was collected by filtration. There was thus obtained Z-3-[2-(4-butoxyphenyl)vinyl]quinuclidine hydrogen chloride as a colourless solid, m.p. 146°-149° C.

实验步骤: (±) 3-(N-Methyl-N-methoxyaminocarbonyl)-1-azabicyclo[2.2.2]octane (D31) (6.0g, 0.03 moles) was dissolved in dry toluene (250ml) and cooled to -70° C. under a nitrogen atmosphere. Diisobutylaluminium hydride (1.5M solution in toluene (45ml, 0.068 moles) was added dropwise. The reaction was then allowed to warm to room temperature over a period of 2h. Hydrochloric acid (2N, 300ml) was added rapidly with vigorous stirring. The aqueous layer was saturated with potassium carbonate and the mixture extracted with chloroform (3×250ml). The combined extracts were dried (Na2SO4) and evaporated to dryness. The residue was distilled in a Kugelrohr to yield the title compound (D32) as a colourless oil (3.6g, 85%) b.p. 100° C. at 1.0 to warm to room temperature over a period of 2h the mixture extracted with chloroform (3×250ml) The combined extracts were dried (Na2SO4) evaporated to dryness The residue was distilled in a Kugelrohr
