tert-Butyl chloroacetate → HCID 70673630, compound

Participants

Reaction Steps

Bis(3-fluorophenyl)methyl quinuclidine-3-carboxylate (70 mg, 0.20 mmol, prepared as in example 4) and tert-butyl 2-chloroacetate (31 μl, 0.21 mmol) were dissolved in acetonitrile (3 ml) and stirred at room temperature overnight. Tert-butyl 2-chloroacetate (28 μl, 0.20 mmol) was added again, and the mixture was stirred for additional 24 hours. Acetonitrile was evaporated, and the resulting crude compound was triturated from Et2O and filtered to obtain 3-((bis(3-fluorophenyl)methoxy)carbonyl)-1-(2-tert-butoxy-2-oxoethyl)-1-azoniabicyclo[2.2.2]octane chloride (42.4 mg, racemic mixture).
