Hydrochloric Acid → n,n-Dimethyl-3-azabicyclo[3.1.0]hexan-1-amine dihydrochloride

Participants

Reaction Steps

To a solution of racemic N,N-dimethyl-3-(phenylmethyl)-3-azabicyclo[3.1.0]hexan-1-amine (0.5800 g, 2.681 mmol) in MeOH (13 mL) was added 1 N aq. HCl (5.4 mL, 5.4 mmol) and 10% Pd/C (50% water, 120 mg). The mixture was hydrogenated under balloon pressure overnight, and then filtered. The solution was concentrated in vacuo and azeotroped with MeOH (4×50 mL) to give crude, racemic N,N-dimethyl-3-azabicyclo[3.1.0]hexan-1-amine dihydrochloride (0.5453 g, >100% crude yield) as a light yellow foam. LCMS: (M+H)+: 127.2.
