Versuchsvorschrift

To a suspension of (R)-quinuclidin-3-yl 2-amino-2-p-tolylacetate dihydrochloride (I109) (116 mg, 0.33 mmol) in DCM (5 ml), were added triethylamine (139 μl, 1.00 mmol) and benzoyl chloride (46.5 μl, 0.40 mmol). The reaction was stirred at RT for 3 hours, and then the solvent was evaporated. The residue was taken up with EtOAc and washed with Na2CO3, water and brine. The organic phase was dried over Na2SO4, filtered and evaporated to obtain (R)-quinuclidin-3-yl 2-benzamido-2-p-tolylacetate (70.0 mg; 55% yield). The product was used in the next step without any further purification.
