Synthetic method of oxadiazon intermediate

The invention discloses a synthetic method of an oxadiazon intermediate. The method comprises the steps: dissolving 2,4-dichloro-5-isopropoxyphenylhydrazine hydrochloride into a chloroform solvent; adding an alkali to complete neutralization at a certain temperature, then standing and separating water; and taking an organic phase, adding an inorganic alkali as an acid-binding agent, stirring and cooling, dropwise adding metered pivaloyl chloride when the temperature reaches a proper temperature, directly separating water after the acylation reaction is qualified through central control analysis to obtain an oxadiazon intermediate 2,4-dichloro-5-isopropoxyphenylhydrazine chloroform solution, and entering the next process. The method is simple to operate and simplified in process, a neutralizing and filtering process is omitted, and the production of alkalized wastewater is greatly reduced; in the acylation step, the inorganic alkali is used as the acid-binding agent, so that a large amount of high-COD and high-ammonia-nitrogen-value wastewater which is difficult to treat is effectively prevented from being generated by adding an organic alkali, the acid-binding agent recovery process is reduced, the labor intensity is greatly reduced, energy is saved, and the economic benefit and the environmental benefit are remarkable.
