실험 절차

N-Ethyl-N-isopropylpropan-2-amine 2-(4-(methoxycarbonyl)phenyl)-2-(phenylamino)acetate (I94) (212 mg, 0.51 mmol), DCC (158 mg, 0.77 mmol), and HOBT (117 mg, 0.77 mmol) are dissolved in dry THF (5 mL). (R)-Quinuclidin-3-ol (195 mg, 1.53 mmol) is added and the mixture is stirred at RT for 2 days. A second portion of DCC (79 mg, 0.38 mmol), HOBT (58.7 mg, 0.38 mmol) and (R)-quinuclidin-3-ol (98 mg, 0.77 mmol) are added and the mixture is further stirred for 24 hours. Then THF is evaporated, the residue is dissolved in EtOAc and washed with NaHCO3, water and brine. The organic phase is dried (Na2SO4), filtered and evaporated. The crude is purified by preparative HPLC. The recovered fractions are evaporated, dissolved in EtOAc and washed with sat. NaHCO3. The organic phase is dried (Na2SO4), filtered and evaporated to afford the desired compound as a colorless oil (42 mg, 21% yield, mixture of diastereoisomers).
