반응 단계
This compound is prepared by the procedure of Example 1 from 2.40 g (0.1 mol) of sodium hydride, 20.63 g (0.1 mol) of 2,6-di-tert-butylphenol, and 34.96 g (0.1 mole) of N-n-octadecylmaleimide in tert-butyl alcohol. The residue is purified by dry-column chromatography (3:1 heptane:ethyl acetate eluent) followed by recrystallization from petroleum ether to give 20.5 g (37%) of a white solid: mp 70°-73° C.
