Reaction Steps

To a solution of (+)-cis-3-((3,5-bis(trifluoromethyl) phenyl)methyloxy)-2-phenyl piperidine prepared from hydrochloride salt (Example 5, 1.0 g) by partitioning between aqueous sodium carbonate and dichloromethane) in dry dichloromethane (5 ml) was added pyridine (0.67 ml), acetic anhydride (0.79 ml) and 4,4-dimethylamine pyridine (10 mg). After the solution had been stirred for 3 h at 23° C., saturated sodium bicarbonate solution was added and the organic phase dried (MgSO4), evaporated in vacuo and chromatographed on silica gel to give the title compound as an oil. Found: C, 59.51; H, 4.90; N, 3.09. Calcd for C22H21NO2F6 ; C, 59.33; H, 4.75; N, 3.14%.
