Reaction Steps

Alternatively, to a stirred suspension of (R)-1-carboxymethyl-3-(2-hydroxy-2,2-diphenyl-acetoxy)-1-azonia-bicyclo[2.2.2]octane trifluoroacetate [Ex. 62] (0.052 g, 0.102 mmol) in dry DMF (5 ml) is added DIPEA (0.053 ml, 0.306 mmol), HATU (0.058 g, 0.153 mmol) and 5,6-Diethyl-indan-2-ylamine hydrochloride (0.035 g, 0.153 mmol). The mixture is left to stir at room temperature overnight. The solvent is removed in vacuo and purification by mass directed preparative HPLC eluting with acetonitrile:water:trifluoroacetic acid yields the titled compound.
