To a solution of (4-methoxyphenyl)(phenyl)methyl quinuclidine-3-carboxylate (37 mg, 0.10 mmol) in EtOAc (1.5 ml), 2-chloro-1-(thiophen-2-yl)ethanone (19 mg, 0.12 mmol) was added. Acetonitrile was added until complete dissolution, and the reaction was stirred at room temperature overnight. The organic solvents were removed under vacuum, and the residue was purified by flash chromatography (DCM/MeOH=9/1) to obtain 3-(((4-methoxyphenyl)(phenyl)methoxy)carbonyl)-1-(2-oxo-2-(thiophen-2-yl)ethyl)-1-azoniabicyclo[2.2.2]octane chloride (16 mg, mixture of diastereoisomers).
