Versuchsvorschrift

To a solution of 2-ethylcyclohexylamine (0.61 mmol) in methanol was added HCl (4.0 M in dioxane, 0.152 mL), and concentrated to give a residue. Phosgene solution (20% in toluene, 6.0 mL) was added, and the reaction was heated at 110° C. overnight. Toluene and excess of phosgene were removed in vacuo to give a residue.
