Water → 4-(3-Dimethylaminoazetidin-1-yl)piperidine trihydrochloride

Participants

Reaction Steps

To a solution of a crude product of N-[1-(1-benzylpiperidin-4-yl)azetidin-3-yl]-N,N-dimethylamine trihydrochloride (14.1 g) in 2-propanol (380 ml)-water (380 ml) was added 10% palladium on carbon (5.0 g), followed by stirring at room temperature under a hydrogen atmosphere for 12 hr. The catalyst was removed by filtration. Concentration of the filtrate provided a crude product of the titled compound as colorless crystals (10.7 g).
