Reaction Steps

With nitrogen substitution, 540 ml of toluene and 138.0 grams (0.9 moles) of phosphorus oxychloride were added and cooled to −10 degrees C. To this mixture, a solution of 243.5 grams (0.9 moles; 1.0 in molar ratio) of 2-heptylundecanol and 91.1 grams (0.9 moles) of triethylamine was dripped, and the mixture was reacted for 12 hours at 0 degrees C. The mixture was then heated to 25 degrees C., and a triethylamine hydrochloride was removed by filtering to obtain 1003.9 grams of a toluene solution of (2-heptylundecyl)dichlorophosphate (34.7% in concentration).
