| titleOfInvention | Synthesis method of acaricide diphenyl phthalate intermediate 3-nitro-4-methoxybiphenyl |
| abstract | The invention relates to a method for synthesizing amidicide diphenyl phthalate intermediate 3 - nitro-4-methoxy phenyl, belonging to the field of pesticide pharmacy, characterized in that 4-halo- 2 nitroanisole and halobenzene Under the action of a catalyst, the reaction gives 3-nitro-4-methoxybiphenyl. The reaction process is as follows: 1) Mix 4-halogeno-2-nitroanisole, halogenated benzene, catalyst and solvent A under a protective gas condition, and raise the temperature to 130-150 ° C, and control the pressure to 7-12 At atmospheric pressure, the reaction ends at 20 to 35 hours; 2) the system is filtered under reduced pressure to remove solid insolubles to obtain filtrate a, and the filtrate a is poured into 3 to 5 volumes of water, and then solvent B is added for extraction, and the organic phase is separated after layering. The desiccant is dried and concentrated to give a solid, which is then recrystallized from solvent C to give 3 - nitro-4- methoxybiphenyl. The invention has fewer steps, higher yield and convenient operation. |
