Procedure

TEA (130 μL, 1.0 mmol) is added to a suspension of the product of Step D (250 mg, 0.9 mmol) in CH2Cl2 (9 mL). Diphenylchlorophosphate (190 μL, 0.9 mmol) is added and the resulting solution is stirred at room temperature for 30 minutes. This solution is added to a solution of (R)-3-aminoquinuclidine (110 mg, 0.88 mmol) in DMF (1 mL). 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. The product is crystallized from CH3CN to yield the desired product (130 mg, 39%). MS for C22H25N3O3 (ESI) (M+H)+ m/z 380.
