What are the synthesis methods of (4-butoxy-2,3-difluorophenyl) boronic acid

The method of synthesizing (4-butoxy-2,3-difluorophenyl) boric acid is often involved in the field of organic synthesis. To obtain this compound, there are two common methods.

First, the halogenated aromatic hydrocarbon is used as the starting material. First, take 4-halogenated-2,3-difluoroanisole, the halogen atom can be bromine or iodine, and undergo a nucleophilic substitution reaction with butanol in the presence of a base to form 4-butoxy-2,3-difluoroanisole. Afterwards, it is subjected to a lithium-halogen exchange reaction and treated with n-butyl lithium and other reagents to generate the corresponding lithium reagent. Then the lithium reagent is reacted with borate esters, such as trimethyl borate, and hydrolyzed to obtain (4-butoxy-2,3-difluorophenyl) boric acid. The key to this path is that the lithium-halogen exchange reaction needs to be carried out under harsh conditions of low temperature and no water and no oxygen to ensure the smooth reaction. The control of the conditions of each step of the reaction is very important. The activity of halogenated aromatics, the type and dosage of bases, the reaction temperature and time will all affect the yield and purity.

Second, synthesized by Grignard reagent method. The Grignard reagent is prepared by reacting 4-halogenated-2,3-difluoroanisole with magnesium chips in anhydrous ether or tetrahydrofuran. The Grignard reagent has high activity, and then reacts with borate esters, such as triisopropyl borate, and then acid hydrolyzes to obtain the target product. Although this method is slightly broader than the former conditions, the preparation of Grignard reagents also requires an anhydrous environment, and the selection of halogenated aromatics, the quality of magnesium chips, and the drying degree of the solvent all have a profound impact on the reaction. During the synthesis process, the reaction intermediates and products need to be separated and purified. The commonly used methods include column chromatography and recrystallization to ensure that the purity of the product meets the required standards.
