A method for synthesizing intermediate oxadiazon

The invention discloses a method for synthesizing intermediate oxadiazon, comprises the following steps: takes amino phenol as an initial raw material; to m-aminophenol acylation reaction is carried out, thereby obtaining a reaction solution A; the reaction solution A to proceed chlorination reaction, to obtain 2, 4 - dichloro - 5 hydroxy acetanilide; to the 2, 4 - dichloro - 5 hydroxy acetanilide etherification reaction, to obtain 2, 4 - dichloro - 5 isopropoxy acetanilide; to the 2, 4 - dichloro - 5 isopropoxy acetyl aniline to deprotected, get 2, 4 - dichloro - 5 isopropoxyaniline. The invention of 2, 4 - dichloro - 5 - isopropoxy aniline synthesis method to avoid the pollution of the environment, but there are few process steps, high yield.

Oxadiazon synthesis method

The invention discloses an oxadiazon synthesis method, wherein 2,4-dichloro-5-nitrophenol and 2-bromopropane are adopted as starting raw materials, and etherification, reduction, diazo reduction, acylation, light cyclization and other reaction process routes are performed to produce oxadiazon. The oxadiazon synthesis method has the following advantages that the operation process is convenient and the total yield is up to 99%; the raw materials are domestic and are easy to obtain, such that the raw material cost is easily reduced and the market competitiveness can be improved; and the solid phosgene is used to replace the hypertoxic phosgene used in the existing process, such that the reaction is stable and safe, the pollutant discharging during the production process is reduced, and the process is the environmentally friendly chemical industry process.
