Phenacyl bromide → 3-((Bis(3-fluorophenyl)methoxy)carbonyl)-1-(2-oxo-2-phenylethyl)-1-azoniabicyclo[2.2.2]octane bromide

Participants

Reaction Steps

Bis(3-fluorophenyl)methyl quinuclidine-3-carboxylate (95 mg, 0.27 mmol, prepared as in example 4) and 2-bromo-1-phenylethanone (58.2 mg, 0.29 mmol) were dissolved in acetonitrile (5 ml) and stirred at room temperature overnight. The solvent was evaporated, and the resulting residue was purified by flash chromatography (DCM/MeOH=95/5 to 9/1) to obtain 3-((bis(3-fluorophenyl)methoxy)carbonyl)-1-(2-oxo-2-phenylethyl)-1-azoniabicyclo[2.2.2]octane bromide (110 mg, racemic mixture).
