Procedure
To a solution of (R)—((R)-quinuclidin-3-yl) 2-phenyl-2-(phenylamino)acetate (diastereomer 1 of I2) (100 mg, 0.30 mmol) in EtOAc (2 ml) and acetonitrile (0.99 ml) was added 3-(chloromethyl)-5-phenyl-1,2,4-oxadiazole (I45) (69.4 mg, 0.36 mmol). The pale yellow solution was stirred at room temperature for 24 hours. The suspension was filtered on a buckner funnel washing with EtOAc (5 ml). The white solid was recovered from the filter to obtain the title compound (98 mg, 62.1% yield).
