Reaction Steps

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 (0.070 ml, 0.408 mmol), HATU (0.097 g, 0.255 mmol) and 5,6-Diethyl-indan-2-ylamine hydrochloride (0.058 g, 0.255 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.
