To prepare N- (2,3-difluorobenzoxy) -3,4-dichloro-2- [ (2-chloro-4-pyridyl) amino] benzamide, the following ancient method can be carried out:
First take the appropriate starting material, take 2,3-difluorobenzyl alcohol as one of them, and place it in the reaction kettle with a suitable halogenating agent, such as thionyl chloride, and add moderate temperature, accompanied by stirring. In this process, the alcohol hydroxyl group will be replaced by the halogen atom to generate 2,3-difluorobenzyl halide. The key to the reaction lies in the precise control of the temperature. If it is too high, there will be many side reactions, and if it is too low, the reaction will be slow. At the same time, 3,4-dichlorobenzoyl chloride can be prepared by co-heating 3,4-dichlorobenzoic acid with thionyl chloride. This acid chloride has high activity and is a key intermediate for subsequent reactions.
Then, 2-chloro-4-aminopyridine is added into an appropriate amount of solvent, such as dichloromethane or N, N-dimethylformamide, and then slowly added to the obtained 3,4-dichlorobenzoyl chloride. This reaction needs to be carried out in a weak base environment, and an appropriate amount of triethylamine or pyridine can be added to bind the acid and promote the reaction. At this stage, the nucleophilic substitution reaction between the amino group and the acyl chloride will occur, resulting in 3,4-dichloro-2-[ (2-chloro-4-pyridyl) amino] benzoyl chloride.
Finally, the previously prepared 2,3-difluorobenzyl halide is mixed with 3,4-dichloro-2-[ (2-chloro-4-pyridyl) amino] benzoyl chloride, and the reaction is heated in a suitable organic solvent in an alkaline environment, such as in the presence of an aqueous solution of potassium carbonate or sodium carbonate. The halogen atom of benzyl halide is connected to the oxygen atom of the carbonyl α-position of benzoyl chloride. After nucleophilic substitution, the final target product is N- (2,3-difluorobenzyloxy) -3,4-dichloro-2 - [ (2-chloro-4-pyridyl) amino] benzamide. After the reaction is completed, the pure product can be obtained by extraction, washing, drying, column chromatography and other separation and purification methods.
Throughout the synthesis process, each step of the reaction needs to be carefully controlled by the reaction conditions. The proportion of raw materials, temperature, pH and other factors have a huge impact on the yield and purity of the product, so it is necessary to be cautious.

This substance is called N- (2,3-difluorobenzoxy) -3,4-dichloro-2-[ (2-chloro-4-cyanophenyl) amino] benzamide, which is a common chemical in the field of organic synthesis.
Its safety and toxicity need to be carefully studied. From a chemical structure point of view, this molecule contains fluorine, chlorine and other halogen atoms, as well as cyano and other specific functional groups. The presence of halogen atoms may make the substance chemically active, under certain conditions, or participate in chemical reactions to form new compounds. Cyanyl is a highly toxic functional group. Once the substance degrades in the environment, if the cyanyl group is released, it may pose a serious hazard to organisms and the environment.
In terms of safety, strict protective measures must be taken when producing, storing and using this substance. When operating, operators should wear professional protective equipment, such as protective clothing, gloves and gas masks, to prevent skin contact and inhalation. Storage should be placed in a cool, dry and well-ventilated place, away from sources of ignition and oxidants, to avoid accidents such as fire or explosion.
In terms of its toxicity, experiments and related studies have shown that compounds containing cyanyl groups are usually toxic to organisms. It may interfere with the enzyme activity and cellular respiration process in the organism, and then affect the normal physiological function of the organism. If accidentally ingested, inhaled or absorbed through the skin, or cause damage to the human nervous system, cardiovascular system, etc., even life-threatening.
In short, for N- (2,3-difluorobenzoxy) -3,4-dichloro-2- [ (2-chloro-4-cyanophenyl) amino] benzamide, it is necessary to fully recognize its latent risk, and strictly follow safety regulations in all links to ensure the safety of personnel and the environment.

The name of this compound is lengthy and complicated, and the market price range of the substance will fluctuate due to various factors, such as production process, purity, market supply and demand, etc. However, due to the lack of more specific information, it is difficult to accurately determine its price range.
In ancient times, the price is often based on the thinness of the substance, the wide range of use, and the difficulty of making it. If the preparation of this substance is difficult, the raw materials are rare, the process is complicated, and it is widely used in important fields such as medicine and chemical industry, the price may be high; if the preparation is easy, the raw materials are common, and the demand is limited, the price may be close to the people.
However, only according to the given name, it is difficult to understand the difficulty of production and the market supply and demand. In order to know the market price range, we should carefully study the chemical raw materials market report, consult industry experts, or check the recent quotations of the chemical products trading platform to obtain a relatively accurate price range.
