A stirred solution of 1.0 g (5 mmol) of 2-tert-butyl-4-mercapto-6-methylaniline, 0.6 g (5 mmol) of N-methylmaleimide and 0.1 g (1 mmol) of triethylamine in 10 mL of toluene is heated at 50° C. for 18 hours. The solvent is removed in vacuo and the residue is purified by flash chromatography (silica gel, 3:2, heptane:ethyl acetate eluent) followed by recrystallization from a heptane:toluene solvent mixture to give 0.8 g (51%) of the title compound as a white solid melting at 92°-94° C.
