Synthesis method

（1)200gethyl acetoacetate and270g SO2CI2, respectively dissolved in100mlbenzene, then in10℃, SO2CI2It is obtained by dropping a benzene solution into a benzene solution of ethyl acetoacetate. (2) resorcin88gandα-Ethyl acetoacetate chloride132gDrip640mlIn concentrated sulfuric acid, the temperature is 5Produced by reaction below ℃3-Chlorine-4-Methyl-7-Hydroxycoumarin. 44g 3-Chlorine-4- Methyl-7-Hydroxycoumarin,29gAnhydrous potassium carbonate is placed together500mlIn methyl ethyl ketone, add dropwise under reflux and stirring40g O,O-Diethylphosphorothioate chloride, reflux2h And get fly poison phosphorus.

Purpose

fly poison Phosphorus-based non-systemic insecticides are particularly effective against dipteran pests. They are also used to control external parasites and are effective in controlling skin flies.
