Versuchsvorschrift

The cold thiocyanogen solution was added to the stirred solution of 1-amino-5-nitronaphthalene, maintaining the temperature at 5°-15° C. The mixture was stirred a further one hour at 5°-15° C. and then made just alkaline (pH 7-8) by addition of concentrated ammonium hydroxide solution. The reaction mixture, after filtering from a small amount of insoluble material, was evaporated to dryness. The solid obtained was stirred with water, filtered, washed and dried.
