1-benzyl-4-(N-methyl-8-azabicyclo[3,2,1]oct-3-yl)-piperazine → 8-Methyl-3-(piperazin-1-yl)-8-azabicyclo[3.2.1]octane

Participants

Reaction Steps

A solution of 1-benzyl-4-(N-methyl-8-azabicyclo[3,2,1]oct-3-yl)-piperazine (4.75 g, 15.88 mmol) in 50 ml methanol was hydrogenated at a pressure of 2.0 atm in the presence of 20% palladium hydroxide on carbon (470 mg) for 30 h. The mixture was then filtered through a pad of celite. The filtrate was concentrated to afford a pale yellow solid quantitatively, which is pure enough for subsequent use.
