A mixture of 2.96 g of stearic acid, 1.87 ml of diphenylphosphoryl azide and 1.21 ml of triethylamine in 90 ml of benzene was heated under reflux for 16 hours. At the end of this time, the mixture was cooled and washed, in turn, with a saturated aqueous solution of sodium bicarbonate and with water. The mixture was then dried, and the solvent was evaporated off under reduced pressure, to give 2.40 g of crude heptadecyl isocyanate.
