Abstract

PURPOSE: To obtain the titled compound useful as an insecticide at a low cost and readily, by reacting a carbamyl chloride with an oxime salt in a specific solvent in the presence of an aqueous solution of caustic soda under specified reaction conditions.
CONSTITUTION: A solution of a carbamyl chloride expressed by formula I (R2 is lower alkyl; R3 is H or lower alkyl), e.g. methylcarbamyl chloride, dissolved in methylene chloride containing substantially no water is mixed with an aqueous solution of caustic soda and an oxime of formula II (R1 is lower alkyl) or a salt thereof, e.g. sodium salt of α-methylmercapto-acetaldoxime, and the pH of the resultant mixture is kept at the neutral to alkaline region and reacted to give the aimed substance of formula III.
EFFECT: The reaction is carried out smoothly even by the caustic soda as an acid binder, and the yield is high without forming by-products.
