Procedure

N-carbomethoxy-5-(2-chloro-5-pyridyl)-7-aza-bicyclo[2.2.1]hept-2-ene 25 (16 mg) was dissolved in 3 ml methanol containing 7 mg 10% palladium on carbon. The mixture was hydrogenated under a slightly elevated pressure of hydrogen for one hour. After removal of catalyst and solvent, the residue was partitioned between ether and aqueous sodium bicarbonate. The aqueous layer was extracted with ether and the combined organic layer was dried over magnesium sulfate. Removal of solvent gave 10 mg of 7-carbomethoxy-2-(3-pyridyl)-7-azanorbornane (12). MS (CI) m/z 233 (M+1), H1 -NMR 3.72, 3.66 (2s, N--COOCH3).
