Reaction Steps

30.6 g of 1,2-diamino-4-(4-propylphenylsulfonyloxy)benzene (see Example 5) and 17.9 g of methyl N-[bis(methylthio)methylene]carbamate in 200 ml of tetrahydrofuran are heated to reflux for four hours. After cooling, the precipitate is filtered off with suction and washed with diisopropyl ether. For purification, it is dissolved in hot dimethylformamide, methanol is added and, after cooling, the product is filtered off with suction, melting point 160° C., decomposition.
