N-[4-(2-Bromoacetyl)Phenyl]Acetamide → (R)-1-[2-(4-acetylamino-phenyl)-2-oxo-ethyl]-3-((R)-2-phenyl-2-phenylamino-acetoxy)-1-azonia-bicyclo[2.2.2]octane bromide

Participants

Reaction Steps

A mixture (R)—((R)-quinuclidin-3-yl) 2-phenyl-2-(phenylamino)acetate (Diastereoisomer 1 of C2) (80.0 mg, 0.24 mmol) and N-(4-(2-bromoacetyl)phenyl)acetamide (60.9 mg, 0.24 mmol) in acetonitrile (2 mL) is heated in a microwave oven at 100° C. for 1 hour (UPLC-MS monitoring: complete conversion). The title compound is isolated by suction filtration and washed with Et2O (98.2 mg, 81% yield, off-white solid, bromide salt, single diastereoisomers).
