(1R*,2R*,5S*,6R*)-8-Benzyl-2-{(1R*)-1-[3,5-bis(trifluoromethyl)phenyl]-2-phenylmethoxyethoxy}1-phenyl-6-(tetrazol-5-yl)-8-azabicyclo[3.2.1]octane (Example 158; 0.403 g, 0.57 mmol), methyl iodide (0.2427 g, 0.107 ml, 1.71 mmol) and potassium carbonate (0.236 g, 1.71 mmol) in acetonitrile (10 ml) were heated at 60° C. for 2 hours. The mixture was quenched with water and concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The organics were collected, dried (MgSO4) and concentrated in vacuo. The residue was purified by flash column chromatography, eluting with 1% methanol/dichloromethane to give the title compounds (isomer A; 60 mg) and (isomer B; 70 mg), together with mixed fractions.
