Versuchsvorschrift

26.3 g (0.1 M) of N-(2,6-dichlorophenyl)-N'-acetylthiourea, 8.1 g (0.12 M as 100%) of potassium hydroxide, 7.7 ml (0.12 M) of methyliodide and 250 ml of ethanol are mixed and are heated in a water bath at 50°-60° for 5 hours. The ethanol is distilled off. The residue in the flask is washed with water and filtered. After recrystallization from isopropanol 14.0 g (50.5 % of the theoretical yield) of N-(2,6 -dichlorophenyl)-N'-acetyl-S-methylisothiourea are isolated.
