反応手順

Ethanol (40 mL) was added to N-tert-butoxycarbonyl-trans-4-(aminomethyl)cyclohexanemethyl azide (1.79 g, 6.67 mmol.) and 5% palladium on carbon (270 mg, 0.15 wt. %) under nitrogen. The reaction mixture was stirred under hydrogen at atmospheric pressure for 6 hours at 23° C. The black suspension was filtered and the filtrate concentrated to give N-tert-butoxycarbonyl-trans-1,4-cyclohexane bis(methylamine) as a yellow oil. The crude amine was taken up into methanol (2.0 mL) followed by addition of hydrogen chloride in dioxane (4.0 M, 2.0 mL, 8.0 mmol.) and ethyl ether (25 mL). The resulting precipitate was collected by filtration to give N-tert-butoxycarbonyl-trans-1,4-cyclohexanebis(methylamine) hydrochloride (1.42 g, 76% yield) as a colorless solid.
