Procedure

To a solution of (R)-quinuclidin-3-yl 2-phenyl-2-(piperidin-1-yl)acetate (100 mg, 0.30 mmol) in EtOAc (2 ml) and acetonitrile (1 ml), was added 3-(chloromethyl)-5-phenyl-1,2,4-oxadiazole (71.1 mg, 0.36 mmol). The reaction was stirred at room temperature for 30 hours and then the solvents were evaporated. The residue was triturated with EtOAc (10 ml) and the solid was collected by suction filtration to obtain the title compound (113 mg, 71% yield) as a yellow solid.
