A solution of 40 g of diisopropylamine in 400 ml of ether is placed in a stirred apparatus; at 10° C., 61.4 g of 4-nitro-2-trichloromethylbenzenesulfenyl chloride in 200 ml of ether is dripped in. After the mixture has been reacted for 4 hours at 25° C., it is filtered and concentrated. There is obtained 70 g (95% of theory) of N,N-diisopropyl-4-nitro-2-trichloromethylphenylsulfenamide; m.p.: 104° C.
