61.4 g of 4-nitro-2-trichloromethylbenzenesulfenyl chloride, dissolved in 500 ml of glacial acetic acid, are mixed with 28 g of 4,6-dimethyl-2-mercaptopyrimidine and 16.4 g of sodium acetate at 20° C. After 12 hours, the precipitate is filtered off, washed with water and dried over potassium hydroxide. 75 g (91% of theory) of 4,6-dimethylpyrimidin-2-yl-dithio-(4-nitro-2-trichloromethylbenzene), of melting point 151° C., are obtained.
