1-Cyclopropyl-8- (difluoromethoxy) -7- [ (1R) -2,3-dihydro-1-methyl-1H-isoindole-5-yl] -1,4-dihydro-4-oxo-3-quinolinecarboxylate methanesulfonate monohydrate, this drug or compound, has a variety of potential side effects, said Jin for Jun in detail.

It may disturb the gastrointestinal tract, causing nausea, vomiting, abdominal pain, and diarrhea. It is also common to cover the spleen and stomach. The transportation and transformation are blocked, and the lift is abnormal, so this is the case. It may also affect the central nervous system, causing headaches, dizziness, restlessness, and restlessness of sleep. Because of the nature of the drug, it enters the brain and disturbs the gods.

Furthermore, there is also a potential damage to the liver and kidneys. The liver is the main one to excrete, the kidney is the main one to store essence, and the drug poison enters the body, or causes liver and kidney dysfunction, and the biochemical source is lacking. And skin allergies are not uncommon, causing rashes, itching, and restlessness on the skin surface. This is a sign that the medicinal qi and qi and blood are competing, and the external one is on the skin.

When using medication, it is necessary to be cautious and carefully observe the changes in the body. If the side use is obvious, seek a good doctor quickly, and adjust the medication method to protect the health of the body.

1-Cyclopropyl-8- (difluoromethoxy) -7- [ (1R) -2,3-dihydro-1-methyl-1H-isoindol-5-yl] -1,4-dihydro-4-oxo-3-quinolinecarboxylic acid methanesulfonate hydrate

1-Cyclopropyl-8- (difluoromethoxy) -7- [ (1R) -2,3-dihydro-1-methyl-1H-isoindole-5-yl] -1,4-dihydro-4-oxo-3-quinoline carboxylic acid methanesulfonate monohydrate, which is a fine product of chemical synthesis. The preparation method is quite complicated and requires delicate steps and precise operation to achieve.

At the beginning, when using suitable raw materials, or specific quinoline derivatives, according to ancient methods, the pure texture must be carefully selected, which is the basis for synthesis. Place it in a suitable reaction vessel and add it in a precise amount without a difference of a millimeter. Afterwards, add a cyclopropyl-containing reagent, which also needs to be purified to ensure its purity. Here, it is crucial to control the temperature and duration of the reaction. Too high or too low temperature, too long or too short time, can cause the reaction to be biased.

Furthermore, the introduction of difluoromethoxy groups requires the help of specific fluorination reagents and methoxylation reagents, and the compatibility of the two needs to be exquisite and appropriate. At the time of the reaction, the protection of inert gas may be required to prevent the intrusion of impurities and damage the process of the reaction. After this step is completed, the structure of the product has taken shape, and it still needs to be modified.

Then, add (1R) -2,3-dihydro-1-methyl-1H-isoindole-5-group. The access of this group requires a suitable catalyst to promote the smooth reaction. The amount and activity of this catalyst affect the efficiency of the reaction and the configuration of the product. After this step, the substituents on the quinoline ring are roughly in place. < Br >
However, the product still needs to be converted into the form of methanesulfonate monohydrate. First, methanesulfonic acid is reacted with it, and the pH and reaction time of the reaction are controlled to make the salt-forming reaction sufficient. Then, through the method of crystallization, an appropriate amount of water is introduced to form monohydrate. When crystallizing, factors such as temperature and solvent volatilization rate are controlled to obtain a pure crystal product. The whole preparation process, as said in the ancient method, requires detailed work and careful steps to prepare high-purity 1-cyclopropyl-8- (difluoromethoxy) -7- [ (1R) -2,3-dihydro-1-methyl-1H-isoindole-5-yl] -1,4-dihydro-4-oxo-3-quinoline carboxylic acid methanesulfonate monohydrate.
