Versuchsvorschrift

2-Nitro-4-thiocyanato-aniline (17.6 g.) was added portionwise to a stirred solution of potassium hydroxide (13.4 g.) in ethanol (210 ml.) cooled below 15° C. After 5 minutes, methyl iodide (12.8 g.) was added to the purple solution and the mixture was allowed to stand overnight at room temperature. The mixture was then poured into water (1100 ml.) and the deep red solid was filtered off, washed with water, and dried to give 4-methylthio-2-nitroaniline (15.8 g.), m.p. 72°-73° C.
