(2S) -2-hydroxy-3- [4- (4-fluoro-3-pyridyloxy) -3,5-dipyridyl] cobalt butyrate, the physical properties of this substance are as follows:
Looking at its shape, it is a crystalline powder under normal conditions. The color is white to yellowish, and the texture is delicate, just like the first snow in winter, delicate and uniform. Its particle size distribution is narrow, so the powder has good fluidity. When poured in the container, it slides down smoothly like fine sand.
Smell its smell, the smell is almost non-existent, as if it is placed in a quiet place, without the slightest disturbing smell.
Measure its melting and boiling point. The melting point is in a specific temperature range, about [X] ° C. At this temperature, the crystal structure gradually melts, like ice disappearing under warm sunlight. The boiling point needs to be determined under specific pressure conditions. At standard atmospheric pressure, the boiling point is [Y] ° C. This is the critical temperature for the transition of matter from liquid to gaseous state.
In terms of solubility, some organic solvents exhibit good solubility in common organic solvents. If in ethanol, with a little heating or stirring, it can be seen slowly blending into a uniform and clear solution, just like fish entering the abyss, fusing seamlessly; in water, its solubility is poor, although it is vigorously stirred, only a small amount of dissolves, just like a stone entering water, difficult to form a whole, and mostly exists in water in a suspended state.
Looking at its density, under normal temperature and pressure, its density is [Z] g/cm ³, which is in a specific range compared with the density of common organic compounds. This density characteristic makes it participate in various reactions or mixed systems, occupying a specific space and affecting the physical properties of the system.
What is the preparation method of sodium (2S) -2-amino-3- [4- (4-hydroxy-3-iodophenoxy) -3,5-diiodophenyl] propionate?
To prepare (2S) -2-hydroxy-3- [4- (4-fluoro-3-pyridyloxy) -3,5-dipyridyl] cobalt propionate, the method is as follows:
First take an appropriate amount of 4-fluoro-3-hydroxypyridine, place it in a clean reaction vessel, add a suitable organic solvent, such as dichloromethane, to help it dissolve and form a uniform solution. Take another 3,5-dibromopyridine and slowly add it to the above solution according to a certain molar ratio. At the same time, add an appropriate amount of base, such as potassium carbonate, to promote the reaction. Warm up to a suitable temperature, about 50-60 degrees Celsius, continue to stir, and when the reaction is over, make the two fully react to form a 4- (4-fluoro-3-pyridyloxy) -3,5-dipyridyl compound.
After the previous reaction is completed, the filtrate is collected by cooling, filtration, etc., and the organic solvent is distilled under reduced pressure to obtain a crude product. Purified by column chromatography to obtain a pure 4- (4-fluoro-3-pyridyloxy) -3,5-dipyridyl compound.
Then take this compound, add another reaction vessel, and add an appropriate amount of organic solvent. Take another (S) -2-hydroxypropionic acid and add it in an appropriate molar ratio. At the same time, add a catalyst, such as triphenylphosphine, etc., and a coupling reagent, such as diisopropylcarbodiimide (DIC), and stir at room temperature. After a few hours, the reaction is completed.
The reaction solution is post-processed, such as extraction, washing, drying, etc., to remove impurities. Purified again by column chromatography to obtain (2S) - 2 - hydroxy - 3- [4 - (4 - fluoro - 3 - pyridyloxy) - 3,5 - dipyridyl] propionic acid.
Finally, take an appropriate amount of (2S) - 2 - hydroxy - 3- [4 - (4 - fluoro - 3 - pyridyloxy) - 3,5 - dipyridyl] propionic acid, dissolve in a suitable solvent, add cobalt salt, such as cobalt acetate, and react at a certain temperature. After the reaction is completed, the crystals are collected by cooling, crystallization, filtration, etc. After drying, (2S) - 2-hydroxy-3- [4 - (4-fluoro-3-pyridyloxy) - 3,5 - dipyridyl] cobalt propionate is obtained. The whole process requires attention to the control of reaction conditions, the selection and treatment of solvents, and the separation and purification of each step to ensure the purity and yield of the product.
