What is the synthesis method of (4-butoxy-2,3-difluorophenyl) boronic acid

To prepare (4-butoxy-2,3-difluorophenyl) boric acid, the following ancient method can be used. Take 4-butoxy-2,3-difluorobrombenzene as the starting material, which is the reaction base. Place it in a clean reactor, which needs to be dry and oxygen-free to prevent impurities from disturbing it.

With anhydrous ether as the solvent, slowly inject it into the kettle, so that 4-butoxy-2,3-difluorobrombenzene is fully dissolved in it to form a uniform liquid. When magnesium chips are introduced again, care should be taken to ensure their smooth entry. Magnesium and 4-butoxy-2,3-difluorobrombenzene will cause a Grignard reaction. This reaction requires mild heat. You can place the kettle in a warm water bath and heat it slightly to promote the reaction to proceed in an orderly manner.

When the Grignard reagent is complete, take another container and fill it with trimethyl borate. Add the prepared Grignard reagent dropwise to the container containing trimethyl borate. The speed of dropwise addition needs to be strictly controlled. If it is too fast, the reaction will be excessive, and if it is too slow, it will take too long. This step is the key. When the two meet, a nucleophilic substitution reaction occurs, and gradually forms (4-butoxy-2,3-difluorophenyl) borate ester intermediates.

After the reaction is completed, it is treated with dilute acid aqueous solution. The concentration of dilute acid, when precisely prepared, too high or too low affects the product. Under the action of dilute acid, the borate ester is hydrolyzed to precipitate (4-butoxy-2,3-difluorophenyl) boric acid.

However, the product is initially formed and still contains impurities. It can be purified by recrystallization. Select a suitable solvent, such as a mixture of ethanol and water, heat the product to dissolve, then slowly cool, and the pure (4-butoxy-2,3-difluorophenyl) boric acid crystals gradually emerge. Then by filtration, pure crystals are obtained, which is the desired product. The whole process requires fine operation at each step to obtain satisfactory results.
