2-Chloro-1-phenylethanone (62.1 mg, 0.40 mmol) was added to a solution of (R)-quinuclidin-3-yl 2-(2-oxopyrrolidin-1-yl)-2-phenylacetate (120 mg, 0.36 mmol) in EtOAc (2.4 ml) and acetonitrile (1.2 ml). The pale yellow solution was stirred at room temperature for three days. The solvent was evaporated and the crude was purified by flash chromatography (DCM/MeOH=9/1) to collect the title compound (118 mg, 66.9% yield) as an off-white spongy solid.
