실험 절차

2-Chloro-1-phenylethanone (17.6 mg, 0.11 mmol) was added to a solution of ethyl 3-(1-(6-methoxypyridin-3-yl)-2-oxo-2-((R)-quinuclidin-3-yloxy)ethylamino)benzoate (C65) (50 mg, 0.11 mmol) in EtOAc (2 ml). The reaction mixture was stirred at room temperature overnight, and then the solvent was evaporated to dryness. The residue was triturated with Et2O and then purified by preparative HPLC (Eluent: CH3CN/H2O) to obtain (3R)-3-(2-(3-(ethoxycarbonyl)phenylamino)-2-(6-methoxypyridin-3-yl)acetoxy)-1-(2-oxo-2-phenylethyl)-1-azoniabicyclo[2.2.2]octane chloride (26.3 mg, 38.9% yield).
