Participants

Reaction Steps

The N-methylsulphonyl-N'-(3,4-dichlorophenyl)-S-methylisothiourea (150 g) obtained in the manner described was suspended in 250 ml of ethyl acetate, and 45 ml of sulphonyl chloride (0.55 mole) was added dropwise to the suspension at a temperature of 50° C. The solvent as well as the formed methanesulphonyl chloride and unreacted sulphonyl chloride was distilled off in the Rotovap, and the crystallising residue was taken up in hexane. After filtration with suction, the resulting N-methylsulphonyl-N'-(3,4-dichlorophenyl)-chloroformamidine had a melting oint of 154° - 156° C.
