Procedure

To a solution of (R)-quinuclidin-3-yl 2-benzamido-2-phenylacetate (C85) (70 mg, 0.19 mmol) in EtOAc (1 ml) and acetonitrile (1 ml), was added 2-chloro-1-phenylethanone (32.7 mg, 0.21 mmol). The reaction was stirred at RT for 24 hours, and then the solvents were evaporated and the residue was triturated with EtOAc (8 ml) to obtain (3R)-3-(2-benzamido-2-phenylacetoxy)-1-(2-oxo-2-phenylethyl)-1-azoniabicyclo[2.2.2]octane chloride (72 mg; 72% yield).
