the preparation method is to add 7-chloro-8-methylquinoline and o-dichlorobenzene in the reaction kettle, add the catalyst azodiisoding, raise the temperature, pass chlorine gas, and control the unreacted quinoline with gas chromatography until the content is ≤ 1%. Desolubilization recovers o-dichlorobenzene to obtain a mixture of 3, 7-dichloro-8-chloromethylquinoline and 3, 7-dichloro-8-dichloromethylquinoline.
