Reaction Steps

PS-DCC (loading: 1.25 mmol/g; 0.93 g, 1.16 mmol) was suspended in dry THF (11.6 ml) and HOBT (0.18 g, 1.16 mmol), 2-morpholino-2-phenylacetic acid hydrochloride (0.15 g, 0.58 mmol) and (R)-quinuclidin-3-ol (0.22 g, 1.75 mmol) were sequentially added. The mixture was shaken overnight and then PS-DCC was filtered off washing with EtOAc and THF. The solution was evaporated and the residue was dissolved in EtOAc (30 ml) and washed with water and then with a sat. NaHCO3. The organic phase was dried (Na2SO4), filtered and evaporated. The crude was purified by flash chromatography (DCM/MeOH=95/5 to 85/15) to obtain (R)-quinuclidin-3-yl 2-morpholino-2-phenylacetate (45 mg, 23.4% yield) as a colorless oil.
