Reaction Steps

(R)-quinuclidin-3-yl 2-(4-methoxyphenylsulfonamido)-2-phenylacetate hydrochloride (C68) (96 mg, 0.22 mmol) was dissolved in DCM and washed with 1M K2CO3. The organic phase was dried over Na2SO4, filtered and evaporated. The resulting solid was dissolved in EtOAc (2 ml) and 2-bromo-1-phenylethanone (49.2 mg, 0.25 mmol) was added. The reaction was stirred at RT for 3 hours, and then it was washed with aq. K2CO3, dried over Na2SO4, filtered and evaporated to obtain (3R)-3-(2-(4-methoxyphenylsulfonamido)-2-phenylacetoxy)-1-(2-oxo-2-phenylethyl)-1-azoniabicyclo[2.2.2]octane bromide (75 mg; 53% yield).
