الإجراء التجريبي

(R)-Quinuclidin-3-yl 2-(3-fluoro-4-methylphenylamino)-2-phenylacetate (C97) (80 mg, 0.22 mmol) and 2-bromo-1-phenylethanone (45.4 mg, 0.23 mmol) are dissolved in acetonitrile (3 mL) and stirred at RT overnight (Conversion complete by UPLC/MS). Acetonitrile is evaporated and the residue is purified by flash chromatography (DCM/MeOH=97/3) affording thetitle compound as a white solid (29 mg, 23% yield, bromide salt, mixture of diastereoisomers).
