Versuchsvorschrift
4.8 G. of 1-amino-2-nitro-4-(prop-2-yn-1-ylthio)benzene in 14 ml. concentrated hydrochloric acid is treated with a solution of 24 g. stannous chloride in 14 ml. concentrated hydrochloric acid at 20°-30° C. After about 30 minutes, the mixture is neutralized with a saturated solution of potassium bicarbonate and chloroform added. The mixture is filtered, the chloroform layer separated, dried and evaporated yielding 1,2-diamino-4-(prop-2-yn-1-ylthio)benzene.
