Looking at its properties, it is often in a solid form, which is easy to store and transport. In terms of solubility, because the molecular structure contains polar groups, it has a certain solubility in polar solvents such as water. However, due to the large non-polar part of the molecule, the solubility in non-polar organic solvents such as benzene and toluene is not good.

Melting point is the key physical property for identifying the compound. It has a specific melting point. When heated to this temperature, the compound changes from solid to liquid. Accurate determination of the melting point can determine the purity of the compound. If it contains impurities, the melting point tends to decrease and the melting range becomes wider.

The density of this compound is also an important physical property. It is related to its space and mass distribution in a specific system. In the fields of preparation research and development, industrial production, etc., it is of guiding significance for material ratio and reaction vessel selection.

In addition, its hygroscopicity cannot be ignored, because it contains groups that can interact with water, and will absorb water under a certain humidity environment. This not only affects the quality and stability of the compound itself, but also requires proper moisture-proof treatment during storage and use to prevent its properties from changing and affecting subsequent applications.

Its main use is more common in the field of medicine, as an important pharmaceutical active ingredient.

In the past, doctors often suffered in the way of treating diseases and saving people, and there was often no good medicine for the symptoms. After the rise of organic chemistry, many new compounds have been created. This compound has been found to have a unique chemical structure and can interact with specific targets in the human body. In terms of antibacterial, it can inhibit the activity of specific enzymes of bacteria, making it difficult for bacteria to grow and multiply normally, just like the ancient art of war "cutting off its grain and grass, trapping its soldiers and horses", so as to achieve the purpose of treating bacterial infectious diseases.

In the clinical application of modern medicine, for respiratory tract infections, urinary system infections and other diseases, many drugs with it as the core ingredient have good curative effect. Because of its delicate structure, it can accurately act on pathogens, and the toxic and side effects are relatively small, just like a good general using soldiers, precision strikes, and does not hurt the innocent. Therefore, in the development and treatment of medicine, this compound hydrochloride hydrate occupies an important position and makes great contributions to protecting people's health.

The synthesis of this compound is an important topic in the field of chemical synthesis. Its synthesis requires multiple and delicate reactions.

The choice of starting materials is crucial. It often starts with compounds with specific functional groups, such as substrates containing fluorine, methoxy and other related structures. The first step, or the introduction of cyclopropyl, can be achieved by a nucleophilic substitution reaction. In this reaction, the cyclopropylation reagent reacts with the substrate precisely, successfully connecting the cyclopropyl group at a specific position. This process requires careful control of reaction conditions, such as temperature, solvent and catalyst dosage.

Then, the construction of the pyrrolido-pyridine structure is a key step. Or through a multi-step reaction, the skeleton of the pyridine is formed first, and then the pyrrolido-pyridine structure is formed by the cyclization reaction. During this period, the control of stereochemistry is particularly important to ensure that the product of the (4aS, 7aS) configuration is obtained. This step often requires the help of special catalysts or chiral aids to guide the reaction to selectively generate the desired configuration.

The structure of quinoline-3-carboxylic acid should not be underestimated. Through multi-step reaction, fluorine, methoxy and other substituents are introduced in sequence, and the quinoline parent nucleus is formed, and finally the 3-position carboxylic acid structure is constructed.

After the main structure is synthesized, it reacts with hydrochloric acid to form a salt, and the conditions are appropriately controlled to form a hydrate. This process also requires fine regulation to obtain the target product 1-cyclopropyl-6-fluoro-8-methoxy-7- [ (4aS, 7aS) -octahydro-6H-pyrrolio [3,4-b] pyridine-6-yl] -4-oxo-1,4-dihydroquinoline-3-carboxylic acid hydrochloride hydrate. The whole synthesis process requires orchestration and precise operation in each step to achieve the target product with high yield and high purity.
