2.37 G. of 1-acetamido-2-nitro-4-thiocyanatobenzene is dissolved in 10 ml. of dimethylformamide under nitrogen and 0.38 g. of sodium borohydride added at 20°-30° C. The mixture is stirred for one hour and then 2.4 ml. of benzylbromide is added. After a further 2 hours the mixture is diluted with water and the product filtered off and washed with water and hexane. Recrystallation from methanol gives pure 1-acetamido-2-nitro-4-benzylthiobenzene.
