To prepare 8 - chloro - 2 - (4 - hydroxyphenyl) - 4 - azabicyclo [5.4.0] undecarbon - 7,9,11 - triene - 9,10 - diol methanesulfonate, the method is as follows:
First take an appropriate amount of 4 - hydroxybenzaldehyde, placed in a clean reactor, dissolved in an organic solvent such as dichloromethane, so that it is uniformly dispersed. In addition, prepare a specific reactant containing a nitrogen-heterobicyclo structure, carefully measured and slowly added to the kettle, and at the same time add an appropriate amount of catalyst. This catalyst needs to be precisely selected according to the reaction characteristics, or it is an organic base, so that the reaction can be carried out gently. Control the temperature in a specific range, or between 30 and 40 degrees Celsius, and continue to stir to make the two fully react. During this process, closely observe the reaction progress, which can be monitored by thin-layer chromatography and other means until the reaction reaches the desired level.
When the reaction is initially completed, carefully transfer the reaction solution to the separation funnel, wash it with appropriate acid and alkali to remove impurities. Then dry it with anhydrous sodium sulfate, and then evaporate under reduced pressure to remove the solvent to obtain a crude product.
Dissolve this crude product in a suitable solvent, such as a mixed solvent of ethanol and water, add methanesulfonic acid, and control the temperature to make the two react, or between 50 and 60 degrees Celsius. After the reaction is completed, cool to room temperature, and crystals can be seen to precipitate. The crystals were collected by filtration with a Brinell funnel and rinsed with a cold solvent to remove surface impurities. The obtained crystals were placed in an oven and dried at a suitable temperature to obtain pure 8-chloro-2- (4-hydroxyphenyl) -4-azabicyclo [5.4.0] undecarbon-7,9,11-triene-9,10-diol methanesulfonate. The whole preparation process requires strict adherence to experimental procedures and attention to safety protection to ensure the purity and yield of the product.

8-Chloro-2- (4-hydroxyphenyl) -4-azabicyclo [5.4.0] Undecarbon-7,9,11-triene-9,10-diol methanesulfonate. When using this product, many matters must be paid attention to.
The first thing to know is its properties. This product must have its unique physical and chemical properties. It can be seen in its shape, whether it is a powder or a crystal, and its color is also different. Knowing this is crucial to distinguish its authenticity and determine its purity. Observing its physical properties, such as melting point and solubility, can help confirm whether it is a desired product.
Furthermore, safety matters must not be ignored. It may be toxic to a certain extent, or there is a risk of irritation to the skin, eyes, and respiratory tract. When taking it, it must be fully protected, wearing protective clothing, protective gloves on hands, and protective goggles on eyes to ensure smooth breathing. Operate in a well-ventilated place. If you accidentally touch it, rinse it with a lot of water immediately. If it is serious, seek medical attention immediately.
Storage is also important. When it is based on its chemical properties, choose a suitable environment. Or need a dry, cool place, protected from heat and light, to prevent its deterioration and decomposition. Separate from other chemicals, do not mix, to avoid chemical reactions and cause danger.
Use the dose, and be sure to control it precisely. According to the specific use, experimental design or treatment plan, take it strictly according to the amount. If the dose is too large, it may cause adverse reactions, such as too strong medicine, causing discomfort to the body; if the dose is insufficient, it will be difficult to achieve the expected effect.
Operation steps, follow the established procedures. Whether it is used in laboratory research or industrial production, follow the standard process and cannot be changed. Every step should be meticulously and carefully. If there is any deviation, the results may be very different, or even lead to safety accidents.
Compatibility taboos must also be known in detail. When combined with certain substances, it may cause adverse reactions and generate harmful substances. Before use, be sure to consult relevant information to clarify its compatibility requirements and avoid improper combinations.
