14.1 g of dodecylamine (0.076 mol) dissolved in 20 ml of chloroform were added dropwise at room temperature with stirring to 100 ml of a solution of 10 g of triethylammonium isocyanate (0.069 mol) in chloroform, prepared according to Example 1. After completion of the addition, the mixture was subsequently stirred at room temperature for 24 hours and heated to reflux for 1 hour. The solvent was evaporated and the residue was recrystallized from chloroform. 9.45 g, i.e. 60% of theory, of dodecylurea were obtained in this way.
