A solution of the (±)-endo and (±)-exo isomers of 3-(3-pyridyl)-2-carboethoxy-2-azabicyclo[2.2.2]oct-5-ene, compound (II), (750 mg, 2.90 mmol) in glacial acetic acid (0.5 mL) and Pd/C (10%) was shaken under a H2 atmosphere in a Parr apparatus for 2 hours. The catalyst was removed by filteration over a bed of Celite and the filterate was basified by addition of a solution of 40% of NaOH in water. The aqueous basic solution was extracted with dichloromethane (4×20 mL) to give 740 mg (98%) of compound (XII).
