실험 절차

To a suspension of (R)-quinuclidin-3-yl 2-amino-2-(4-methoxyphenyl)acetate dihydrochloride (I106) (325 mg, 0.89 mmol) in DCM (10 ml), were added triethylamine (374 μl, 2.68 mmol) and benzoyl chloride (125 μl, 1.07 mmol). The reaction was stirred at RT for 4 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-(4-methoxyphenyl)acetate (145 mg; 41% yield). The product was used in the next step without any further purification.
