Reaction Steps

(1R*,2R*,5S*,6R*)-2-Benzylamino-8-benzyl-1-phenyl-6-(1-methyl-1H-tetrazol-5-yl)-8-azabicyclo[3.2.1]octane (Description 33a; 57 mg, 0.12 mmol) was dissolved in ethanol (5 mL) and treated with 1,4-cyclohexadiene (5 mL), followed by 10% palladium on activated charcoal (50 mg). The suspension formed was heated at reflux for 72 hours, then cooled and filtered. The filtrate was concentrated, and the residue taken up in ethyl acetate (2 mL) and treated with ethereal hydrogen chloride (2 mL, 1M). The solid formed was removed by filtration, washed with diethyl ether and dried to give the crude title compound as a solid (27 mg). MS (ES+) 285 (M+H).
