61.4 g of 4-nitro-2-trichloromethylbenzenesulfenyl chloride are reacted with 26.6 g of 4-hydroxy-2-mercaptopyrimidine by a method similar to that described in Example 7. Water is then added and the product is filtered off. 75 g (94% of theory) of 4-hydroxypyrimidin-2-yl-dithio-(4-nitro-2-trichloromethylbenzene), of melting point 174° C., are obtained.
