Reaktionsschritte
cis-(2-Pyrrolidin-1-yl-cyclohexyl)-carbamic acid tert-butyl ester (1.8 g, 6.7 mmol) was dissolved in dioxane. 4H HCl in dioxane (17 mL, 67 mmol) were added and the reaction mixture was stirred at room temperature overnight. The solvent was evaporated off. The residue was crystallized with ethanol and yielded cis-2-pyrrolidin-1-yl-cyclohexylamine dihydrochloride as a white solid (1.37 g, 85%), MS: m/e=169.2 [(M+H)+].
