1H-Benzimidazole, 2-[(R)-[[3-methyl-4-(2,2,2-trifluoroethoxy)-2-pyridinyl]methyl]sulfinyl]-

This is the chemical structure of 2- [ (R) - [[3-methyl-4- (2,2,2-trifluoroethoxy) -2-pyridyl] methyl] sulfinyl] -1H-benzimidazole. Among its structures, 1H-benzimidazole is the root, which is a thick heterocyclic structure containing two nitrogen atoms, with unique aromatic and chemical activity. At the 2 position, there is a delicate side chain connected. The side chain starts with a sulfinyl group of the (R) configuration, which is connected to the benzimidazole 2 position at one end and a specific pyridyl derivative at the other end. On the pyridine ring, the 3 position is methyl, and the 4 position is connected to 2,2,2-trifluoroethoxy. The introduction of fluorine atoms in this structure can significantly affect the molecular physical and chemical properties, such as lipophilicity and stability, due to the high electronegativity of fluorine. The spatial position and electronic effect of the methyl group connected to the sulfinyl group at the 2 position of the pyridine ring also have a great impact on the overall molecular properties. Such a structure endows the compound with unique chemical and physical properties, which may have important research and application value in the fields of medicinal chemistry and organic synthesis.

1H-benzimidazole, 2- [ (R) - [[3-methyl-4- (2,2,2-trifluoroethoxy) - 2-pyridyl] methyl] sulfinyl] This material has many physical properties. Its shape or solid, because the molecular structure contains a variety of groups, resulting in a specific range of melting points. The structure of benzimidazole ring and pyridyl group in the molecule makes the intermolecular force complex, and the melting point is expected to be not low, or between 150 ° C and 250 ° C. < Br >
In terms of solubility, because it contains polar sulfinyl groups, fluorine and methyl and other non-polar parts, it has a certain solubility in polar organic solvents such as ethanol and acetone, but the solubility in water is not good, because the overall structure is not strongly polar.
Appearance may be white to light yellow powder, because the molecular structure has the characteristics of light absorption and reflection. The electron transition and conjugation system in the molecule cause it to absorb at specific wavelengths of light, and the color range is displayed macroscopically.
Its density is also related to the structure. The fluorine atoms in the molecule have a large relative mass and a small radius, so that the overall density is slightly higher than that of the general analogue containing hydrocarbon, nitrogen and oxygen, or 1.3-1.5 g/cm ³. The compactness of the molecular structure and the arrangement of atoms determine its density in this range.

It is often used as an active ingredient in anti-ulcer drugs. This ingredient can efficiently inhibit gastric acid secretion, and by virtue of its specific effect on the proton pump, blocks the key link of gastric acid production, thereby effectively treating gastric acid-related diseases such as gastric ulcers, duodenal ulcers, and reflux esophagitis.
From the perspective of drug development, its unique chemical structure endows it with good pharmacological activity and selectivity, which can precisely act on the target, reduce the interference with other physiological processes, and improve the safety and effectiveness of the drug. And in the development of pharmaceutical preparations, by optimizing the dosage form and formula, its stability and bioavailability can be further enhanced, and it can be better absorbed and utilized by patients.
In addition, with the continuous deepening of medical research, the research on this compound is also continuing to expand, exploring its potential in the treatment of more gastrointestinal diseases, as well as the possible synergistic effects when combined with other drugs, in order to provide more abundant and effective means for clinical treatment.

To prepare 1H-benzimidazole, 2- [ (R) - [[3-methyl-4- (2,2,2-trifluoroethoxy) -2-pyridyl] methyl] sulfinyl], there are many methods and each has its own strengths.
First, 3-methyl-4- (2,2,2-trifluoroethoxy) -2-pyridyl formaldehyde is used as the starting material, and it can be obtained gradually by condensation with thiol and then oxidizing thioether to sulfoxide with a suitable oxidant. In this process, attention should be paid to the precise control of the reaction conditions. When condensation occurs, temperature and catalyst dosage affect the reaction rate and yield. In the oxidation step, the choice of oxidizing agent and the reaction time are also critical. If it is not done properly, excessive oxidation will cause the increase of impurities.
Second, starting from 3-methyl-4- (2,2,2-trifluoroethoxy) -2-pyridyl methyl halide, it is reacted with thioacetate to form a sulfide intermediate. Subsequent hydrolysis and oxidation can also reach the target product. In this approach, the halide activity is high, and the reaction is easy to proceed, but it is necessary to pay attention to the occurrence of side reactions; the hydrolysis step requires strict conditions, otherwise the product is impure.
Furthermore, the pyridyl-containing fragment can be connected to the benzimidazole precursor by means of the coupling reaction catalyzed by the transition metal, and the sulfinyl group can be introduced later. Although this method is efficient, the transition metal catalyst is expensive, and it is difficult to separate and recover, which also requires high reaction equipment and operation.
All synthesis methods have their own advantages and disadvantages. In actual operation, the choice should be made carefully according to factors such as the availability of raw materials, cost considerations, and product purity requirements.

1H-benzimidazole, 2 - [ (R) - [[3-methyl-4 - (2,2,2-trifluoroethoxy) - 2-pyridyl] methyl] sulfinyl] This product is in the market, and there are many common specifications. As in the classical Chinese words of "Tiangong Kaiwu", its specifications vary depending on the use and preparation method.
In the genus of medicinal stones, for precise healing of diseases, it is often made into a subtle agent or a powder according to the needs of medicinal power and treatment, and the particle size is subdivided. Those who are as fine as dust are suitable for internal administration to reach the viscera; or pills, with different sizes, weighed according to the medicinal power. The small ones are like millet, which is easy to swallow, so as to slow down the medicinal power; the large ones are like sycamore seeds, which can concentrate the medicinal power and release for a long time.
If used in the chemical industry, in response to different reaction conditions and product requirements, the purity specifications vary greatly. High purity, impurities are fine, almost pure, used in delicate synthesis to ensure the purity of the reaction; slightly less pure, can also be applied to the general process, can take into account the cost and efficiency. And its form is either crystal, crystal form is regular, easy to measure and use; or paste, conducive to dispersion and mixing, and blending with other things. All these specifications are designed for use, to do their best and be used by the world.
