6-(1-(3-Pyridinyl)-2-nitroethyl)-1-azabicyclo[2.2.2]octan-3-one (14.0 g, 0.046 mol) was dissolved in ethanol (200 mL), and then Raney nickel was added under nitrogen. The mixture was subjected to hydrogenolysis (40 psi H2) for 48 h and then filtered through Celite and concentrated by rotary evaporation to a crude brown residue. The residue was purified by column chromatography, using chloroform/methanol/ammonia (80:20:1, v/v) as eluent, to yield 3-pyridin-3-yl-1,5-diazatricyclo[5.2.2.0<2,6>]undecane as a yellow oil (8.0 g, 67%).
