(1R*,2R*,5S*,6R*)-8-Benzyl-2-{(1R*)-1-[3,5-bis(trifluoromethyl)phenyl]-2-hydroxyethoxy}-6-cyano-1-phenyl-8-azabicyclo[3.2.1]octane (Example 156; 0.7749 g, 1.35 mmol), benzyl bromide (0.4618 g, 0.321 ml, 2.7 mmol), 18-crown-6 (0.714 g, 2.7 mmol) and sodium hydride (0.1037 g, 4.32 mmol) in THF (6 ml) were heated at 60° C. for 1 hour. The mixture was diluted with water and extracted into ethyl acetate. The organics were collected and dried (MgSO4) and concentrated in vacuo. The residue was purified by flash column chromatography eluting with 15% ethyl acetate/iso-hexane, to afford the title compound as a clear oil (712 mg, 79%).
