実験手順

TEA (50 μL, 0.35 mmol) is added to a suspension of 4-phenoxybenzoic acid (75 mg, 0.35 mmol) in CH2Cl2 (1 mL). Diphenylchlorophosphate (62 μL, 0.3 mmol) is added and the resulting solution is stirred at room temperature for 30 minutes. A solution of (R)-3-aminoquinuclidine (1M in DMF, 0.2 mL, 0.2 mmol) is added and the resulting solution is stirred overnight at room temperature. MeOH is added and the mixture is poured through a column of AG50W×2 ion exchange resin (H+ form). The resin is washed with MeOH and then the product is eluted with 5% TEA in MeOH. The eluent is evaporated to dryness to yield the desired product (49 mg, 76%). MS for C20H22N2O2 (ESI) (M+H)+ m/z 323.
