반응 단계
A mixture of 13.9 g (0.055 mole) N-(2-hydroxyethyl)lauramide, 13.9 g (0.05 mole) 3(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid, 0.5 g Tyzor TBT catalyst and 100 ml xylene was refluxed until evolution of water ceased (3 hours). The xylene was removed by vacuum stripping. The residue was taken up in acetonitrile. White crystals separated upon cooling at about -10° C. The acetonitrile was decanted and the recrystallization was repeated. The last traces of acetonitrile were removed under vacuum, and the title product thus obtained was a yellow oil at room temperature.
