The synthesis method of 2-amino-7- (1-methylethyl) -5-oxo-5H-[ 1] benzopyrano [2,3-b] pyridine-3-carboxylic acid has been known for a long time.
First take an appropriate amount of starting materials, often based on pyridine and benzopyran compounds with specific substituents. In a clean reactor, control the temperature to a suitable range, generally about a mild temperature range, such as 30 to 60 degrees Celsius, and add a specific catalyst, which needs to be able to effectively promote the reaction or be a complex of metal salts and organic ligands.
Then, slowly add an appropriate amount of reagent dropwise. This reagent can react with the starting material such as nucleophilic substitution or cyclization. The rate of dropwise addition needs to be finely regulated to prevent overreaction. After the dropwise addition, continue to stir to fully mix the reaction system. The number of reactions depends on the reaction process, or the reaction time needs to be extended to 8 to 12 hours.
After the reaction is completed, the product is separated from the reaction mixture by a suitable separation method, such as column chromatography. First select a suitable eluent, and separate the product and impurities on the chromatographic column according to the difference in polarity between the product and the impurities. Collect the eluent containing the product, and then perform operations such as reduced pressure distillation to remove the solvent and obtain a crude product.
The crude product needs to be further refined, usually by recrystallization method. Select an appropriate solvent, heat to dissolve the crude product, filter while hot to remove insoluble impurities, then slowly cool down, crystallize the product, filter and dry, and finally obtain pure 2-amino-7- (1-methylethyl) -5-oxo-5H-[ 1] benzopyrano [2,3-b] pyridine-3-carboxylic acid. This synthesis method requires fine control of all aspects in the operation to obtain satisfactory yield and purity.

2-Amino-7- (1-methylethyl) -5-oxo-5H-[ 1] benzopyrano [2,3-b] pyridine-3-carboxylic acid is in the market, and its price is variable and difficult to determine. Due to the complex market conditions, changes in supply and demand, poor quality, and sources of manufacture and sale all affect its price.
This compound has various uses. It is used in pharmaceutical and chemical industries or as an essential agent. It is also commonly used in scientific research. The demand is different, and the price is also different. If the quality is high, the standard of high purity, for pharmaceutical research and development, the price will be high; if it is only for general chemical use, the purity requirements are slightly lower, and the price may be slightly reduced.
And the difficulty of its production, the price of raw materials is also related to the price. If the preparation requires rare raw materials and complicated processes, the cost will be high, and the price will not be low; if the raw materials are easy to obtain and the production method is simple, the price may be controllable. And the situation of market supply and demand is also heavy, the demand exceeds the supply, and the price often rises; if the supply exceeds the demand, the price may fall.
Therefore, if you want to know the exact price range, you need to study the market conditions in detail and consult the suppliers before you can get a more accurate price.
