Participants

Reaction Steps

To a suspension of (R)-quinuclidin-3-yl 2-amino-2-phenylacetate dihydrochloride (I25) (150 mg, 0.45 mmol) in DCM (5 ml), were added triethylamine (188 μl, 1.35 mmol) and cyclohexyl carbonochloridate (78 μl, 0.54 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 water and brine, dried over Na2SO4 and evaporated to dryness to obtain (R)-quinuclidin-3-yl 2-(cyclohexyloxycarbonylamino)-2-phenylacetate (105 mg; 60% yield).
