The acetone is distilled off. The product in the flask is washed with water and is filtered. After drying N-(2,6-dichlorophenyl)-N'-acetyl-S-benzylisothiourea is obtained with a melting point of 84°-95° C. After being recrystallized twice from ethanol it has a melting point of 99°-101° C., whereby 1.7 g are isolated (24% of the theoretical yield).
