Procedure

(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; 0.3 g, 0.5 mmol), methyl iodide (0.04 g, 0.02 ml, 0.3 mmol), sodium hydride (0.04 g, 1.6 mmol) and 18-crown-6 (0.3 g, 1 mmol) in N,N-dimethylformamide (3 ml) was heated at 60° C. for 1 hour. The mixture was quenched with water and extracted with ethyl acetate. The organics were collected, dried (MgSO4) and concentrated in vacuo. The residue was purified by flash column chromatography, eluting with 30% ethyl acetate/hexane. The title compound was isolated as a white crystalline solid (285 mg, 97%).
