関与物質

反応手順

To a stirred solution of 1.00 g (5.1 mmol) of 2-tert-butyl-4-mercapto-6-methylaniline and 0.05 g (0.5 mmol) of triethylamine in 5 mL of toluene at room temperature is added dropwise a solution of 1.16 g (5.1 mmol) of di-n-butyl maleate in 5 mL of toluene. The reaction mixture is stirred for 18 hours at room temperature. The solvent is removed in vacuo and the crude product is purified by flash column chromatography (silica gel, 85:15, heptane:ethylacetate eluent) to give 0.60 g (28%) of the title compound as a colorless liquid.
