Versuchsvorschrift

5 G. of 1-amino-2-nitro-4-thiocyanatobenzene in 20 ml. of dimethylformamide is heated under nitrogen with 0.97 g. of sodium borohydride in 20 ml. of dimethylformamide at not greater than 30° C. The mixture is stirred at 15° to 20° C for 1 hour, then treated with 6 g. of 1-iodo-2,2,3,3-tetrafluoropropane. The mixture is heated to 100° C for 4 hours, then cooled and diluted with water. The mixture is extracted with chloroform and the chloroform is evaporated to yield a red oil. Chromatography on silica gel gives 2-nitro-4-(2,2,3,3-tetrafluoropropylthio) aniline.
