反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 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. The residue is purified by dry-column chromatography (3:1 heptane:ethyl acetate eluent) followed by recrystallization from petroleum ether

实验步骤: A stirred solution of 2.8 g (14 mmol) of 2-tert-butyl-4-mercapto-6-methylaniline, 5.0 g (14 mmol) of N-octadecylmaleimide and 0.1 g (1 mmol) of triethylamine in 50 mL of toluene is heated at 50° C. for 18 hours. The solvent is removed in vacuo and the residue is purified by preparative HPLC (silica gel, 4:1, heptane:ethyl acetate eluent) to give 4.3 g (55%) of the title compound as a caramel-colored liquid. The solvent is removed in vacuo the residue is purified by preparative HPLC (silica gel, 4:1, heptane:ethyl acetate eluent)
