Procedure
A mixture of (1R*,2R*,5S*,6S*)-8-benzyl-2-{[3,5-bis(trifluoromethyl)phenyl]-methoxy}-6-fluoro-6-(2-methyl-2H-tetrazol-5-yl)-1-phenyl-8-azabicyclo[3.2.1]octane (Example 173b; 74 mg, 0.12 mmol) was treated with an etheral solution of hydrogen chloride and concentrated. The residue was dissolved in ethanol (20 ml) and 10% palladium on charcoal (109 mg) was added. The mixture was stirred under hydrogen atmosphere (1 atm) at +60° C. for 30 minutes. The reaction mixture was cooled to room temperature, flushed with nitrogen gas and filtered through a pad of Celite™. The filtrate was concentrated and the residue was purified by chromatography on silica gel (dichloromethane:methanol:ammonia) to give the title compound (52 mg, 82%). The hydrochloride salt of the title compound was prepared by treatment with ethereal HCl.
