実験手順

A mixture of 5′-nitrospiro[1-azabicyclo[2.2.2]octane-3,2′(3′H)-furo[2,3-b]pyridine](1.4 g, 5.36 mmol), and 10% palladium on carbon (48% water wet, 270 mg) in methanol (90 mL) was hydrogenated for 1 hour at 50 psi of hydrogen. The catalyst was filtered off through a pad of celite and the solvent was evaporated under reduced to obtain the amine (1.2 g, 5.25 mmol, 98%) as a tan solid: electrospray MS (m/z, relative intensity) 232 ([MH]+, 100).
