Reaction Steps

A solution of 20.28 g (53.5 mmol) of 6,8-bis(phenylmethyl)-6,8-diazabicyclo[3.2.2]nonane dihydrochloride in 400 of 2:1 methanol-water was hydrogenated using 2.5 g of 20% Pd/C catalyst. The reaction mixture was filtered and evaporated to dryness. The residue was triturated with 2-propanol and filtered to give 9.84 g of 6,8-diazabicyclo[3.2.2]nonane, dihydrochloride, mp 300°-310° dec (92%).
