In a 1-liter flask fitted with a stirrer and reflux condenser is added 137.5 grams (0.525 mole) of p-n-dodecylaniline, dissolved in 138 ml of toluene. To this is added over a 15-minute period 57.5 ml of acetic anhydride. The temperature rises from 40° to 80° C. After all the acetic anhydride is added, the reaction mixture is stirred at 40° C. for 3 hours. The reaction mixture is then cooled to yield the crude product which is recrystallized from 800 ml of methanol to give 151.1 grams of the above-named material as a solid melting at 100°-102° C.
