To prepare 7-bromo-4-methoxyisobenzaldehyde, there are three methods.
First, start with 4-methoxybenzoic acid. First, 4-methoxybenzoic acid is co-heated with thionyl chloride to obtain 4-methoxybenzoyl chloride. Then 4-methoxybenzoyl chloride reacts with aluminum bromide and copper bromide in carbon disulfide to introduce bromine atoms to obtain 3-bromo-4-methoxybenzoyl chloride. After hydrolysis and oxidation, the target product can be obtained. This step is slightly complicated, but the raw materials are easy to obtain, and the conditions are not harsh.
Second, 4-methoxybenzaldehyde is used as the starting material. In a suitable solvent, under the action of a catalyst such as Lewis acid, it reacts with bromine. This reaction requires precise temperature control. Because the aldehyde group of benzaldehyde is an ortho-site locator and the ortho-site resistance is affected, 3-bromo-4-methoxybenzaldehyde is mainly obtained. After that, the methoxy group is introduced into the aldehyde group through a specific reaction to obtain 7-bromo-4-methoxyisobenzaldehyde. This method is relatively simple, but the selectivity of the reaction needs to be carefully adjusted to increase the yield of the target product.
Third, take 2-bromo-5-methoxytoluene as the starting material. First oxidize it to 2-bromo-5-methoxybenzoic acid, commonly used oxidants such as potassium permanganate, etc. Then through a series of reactions, such as converting carboxyl groups into aldehyde groups, this process may involve reduction, specific reagent action and other steps, and finally obtain 7-bromo-4-methoxyisobenzaldehyde. The choice of raw materials for this route is slightly biased, but if the operation is proper, the yield is good, and the reaction mechanism of each step is clear, which is beneficial for the optimization of the synthesis process.

7-Fluoro-4-methoxy isobenzofuran needs to pay attention to many matters during storage and transportation.
For storage, first, it should be found in a cool and dry place. If this medicine is placed in a high temperature and humid place, it is easy to cause its chemical properties to change, or cause decomposition and deterioration, resulting in damage to its quality and efficacy. Second, it is necessary to ensure that the storage place is well ventilated. Because it may evaporate special odors or harmful gases, good ventilation can be dispersed in time to prevent accumulation and cause safety hazards, and it can also keep the air in the storage environment fresh. Third, it should be strictly stored separately from oxidants, acids, alkalis and other substances. This compound is chemically active, comes into contact with the above substances, or triggers violent chemical reactions, such as combustion, explosion and other serious accidents.
When transporting, bear the brunt, and the packaging must be tight and stable. Appropriate packaging materials must be selected to ensure that it is not damaged by vibration or collision during transportation, and to prevent drug leakage. Second, the transportation vehicle must have a good ventilation and temperature control device. Ventilation can dissipate harmful gases that may be generated, and the temperature control can maintain a suitable temperature to avoid affecting the stability of the drug due to too high or too low temperature. Third, the transportation personnel need to be professionally trained. Familiar with the characteristics, risks and emergency treatment methods of 7-fluoro-4-methoxy isobenzofuran, in the event of an emergency, it can respond quickly and correctly. Fourth, the transportation process should strictly follow relevant regulations and standards. Conduct necessary transportation permits and procedures to ensure legal compliance of transportation, and the transportation route should avoid densely populated areas and environmentally sensitive areas to reduce the harm to the public and the environment in the event of an accident.
