Versuchsvorschrift
2-Chloro-1-(thiophen-2-yl)ethanone (30.6 mg, 0.19 mmol) was added to a solution of (R)-quinuclidin-3-yl 2-(4-fluorophenyl)-2-(piperidin-1-yl)acetate (60 mg, 0.17 mmol) in EtOAc (3 ml). The reaction was stirred at room temperature for 16 hours. Et2O was added the precipitate was collected by filtration and purified by flash chromatography (DCM/MeOH/NH4OH=97/3/0.3) to obtain (3R)-3-(2-(4-fluorophenyl)-2-(piperidin-1-yl)acetoxy)-1-(2-oxo-2-(thiophen-2-yl)ethyl)-1-azoniabicyclo[2.2.2]octane chloride (23 mg, 26.2% yield) as a white solid.
