For example, 8.6 g (50 mmol) of 1-undecanol, 5 ml (1.07 eq.) n-propyl isocyanate and 50 ml diethyl ether were heated in a stainless steel bomb at 65° for 72 hours. Solvent and excess isocyanate were removed on a rotary evaporator and the residue was crystallized from hexane to give 11.5 g (89%) of 1-undecyl propylcarbamate, mp 45°-45.5°.
