FIELD: chemistry.
SUBSTANCE: invention relates to a method for preparation of a sulphylimine compound, such as N-cyano-S-methyl-S-[1-(6-trifluoromethyl-3-pyridinyl)ethyl]sulfinylimine, or another substituted sulphylimine compound which includes reaction of a sulfide compound, cyanamide, hypochlorite and base, and sulphide compound oxidizing to produce a sulphylimine compound. A buffer compound, such as a phosphate buffer, may be optionally used in the reaction.
EFFECT: method improvement.
