Reaction Steps

Benzyl bromide (0.134 ml) was added to a mixture of (+)-cis-3-((3,5-bis(trifluoromethyl)phenyl)methyloxy)-2-phenyl piperidine (prepared from the hydrochloride salt, Example 5) (0.5 g) and potassium carbonate (0.468 g) in N,N-dimethylformamide (2 ml) and the mixture stirred at 23° C. for 2.5 h. Water (20 ml) was added and the mixture extracted with ethyl acetate (3×15 ml). The combined organic extracts were washed with water (1×10 ml) and brine (1×10 ml) then dried (K2CO3) and concentrated to leave an oil. Purification on silica gel eluting with hexanes-ethyl acetate (19:1 then 9:1 then 4:1 then 1:1) provided the title compound as a solid, m.p.=89°-93° C. Found: C, 66.11; H, 5.25; N, 2.81. Calcd. for C27H25NOF6 ; C, 65.71; H, 5.11; N, 2.84%.
