In a 1-liter three-neck, round-bottom flask equipped with a thermometer, stirrer, dropping funnel and condenser were placed 36.9 g of N-(2,2-dimethyl-3-hydroxypropyl)-stearamide, 25 ml of triethylamine and 250 ml of toluene. To this stirred mixture was added 29.6 g of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl chloride. The mixture was filtered, stripped, and the residue was dissolved in hot methanol. The 2,2-dimethyl-3-stearamidopropyl stearate, melting at 60°-62° C. was isolated. The methanol solution was stripped, and the residue was dissolved in acetonitrile. The title compound was isolated; it melted at 44° C.
