To a solution of 3,5-di-t-butyl-1,2-benzoquinone (2.2 q) in methanol (15 ml) cooled in an ice bath was added 2-aminothiophenol (1.38 g) and the mixture was stirred for 2 hours. A solid precipitate was filtered off and crystallized from heptane to yield the title compound m.p. 202°-212° (dec.). From the methanol filtrate there was obtained, after chromatography and crystallization, an additional crop of the title compound.
