実験手順

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 -5° C. is added dropwise a solution of 0.44 g (5.1 mmol) of methyl acrylate in 5 mL of toluene. The reaction mixture is stirred for 24 hrs at room temperature. The solvent is removed in vacuo and the crude product is purified by flash column chromatography (silica gel, 95:5, heptane:ethyl acetate eluent) to give 0.95 g (66%) of the title compound as a colorless liquid.
