Participants

Procedure

5.2 g (0.02 M) of N-(2,6-dichlorophenyl)-N'-acetylthiourea, 1.3 g (0.012 M) of sodium carbonate, 1.5 ml (0.024 M) of methyliodide and 200 ml of acetone are boiled under energetic shaking for 10 hours. The acetone is distilled off and the residue is washed and then filtered. After drying 4.9 g (88.5% from the theoretical yield of N-(2,6-dichlorophenyl)-N'-acetyl-S-methylisothiourea are obtained with a melting point 135-139° C. After recrystallization from ethanol, the melting point of the product is 139°-141° C.
