Reaction Steps

A mixture of the enantiomer (R)-(−)-5′-nitrospiro[1-azabicyclo[2.2.2]octane-3,2′(3′H)-furo[2,3-b]pyridine] (3.8 g, 13.3 mmol) and 10% palladium on carbon (48% water wet, 270 g) 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 pressure; the residue was purified by flash chromatography (eluting with ammoniated chloroform/methanol, 95:5 to 85:15), provided the title compound (2.5 g, 10.8 mmol, 81%): electrospray MS (m/z, relative intensity) 232 ([MH]+, 100).
