Reaction Steps

A solution of HCl (4.0 N in 1,4-dioxane, 2 ml)) was added to a mixture of tert-butyl (1R,2R)-2-((1S,4S,6S)-2-(4-cyanophenyl)-2-azabicyclo[2.2.1]heptan-6-ylamino)cyclohexylcarbamate (445 mg, 1.084 mmol) in 1,4-dioxane (2 ml). The starting material formed a gum. MeOH (1 mL) was then added. Eventually all solids went into solution. The reaction was stirred at rt for 2 hrs. The reaction mixture was concentrated to give 4-((1R,4R,6S)-6-((1R,2R)-2-aminocyclohexylamino)-2-azabicyclo[2.2.1]heptan-2-yl)benzonitrile bishydrochloride (440 mg, 1.084 mmol, 100% yield) of an off white solid. Calcd. for C19H26N4 m/z 310.4, found: 311.2 (M+H)+.
