Procedure
A 4N-hydrochloric acid/1,4-dioxane solution (4.5 ml) was added to a solution of tert-butyl 3-[(dibenzylamino)carbonyl]cyclohexanecarbamate (0.749 g, 1.773 mmol) in tetrahydrofuran (4.5 ml) and stirred overnight. The solvent was distilled off under reduced pressure, followed by replacement with toluene (twice), whereby 3-amino-N,N-dibenzylcyclohexanecarboxamide monohydrochloride (0.848 g, >99%) was obtained.
