To prepare 4- (9H-xanthoxy-9-oxycarbonylamino) - 1-methyl-1H-pyrazole-2-carboxylic acid, please refer to the method of "Tiangong Kaiwu", which is detailed in the ancient method as follows:
The choice of starting material is very important. When a compound with a specific structure is used as a base, the target product can be obtained after multiple steps of delicate transformation.
The first step is to select a suitable compound containing xanthoxy-ton structure. This compound needs to have a reactive active group at a specific check point. With the action of a reagent, under the reaction conditions of delicate regulation, such as precise temperature control and solvent selection, the substitution reaction occurs. In this process, the active group is cleverly combined with the reagent to introduce the required oxycarbonyl amino group to form the key intermediate.
Then, the compound containing methyl and pyrazole structures is taken to meet the above intermediates. After condensation reaction, the connection between the pyrazole ring and the xanthene structure is constructed. In this step of the reaction, attention should be paid to the acid-base balance of the reaction environment, because it has a profound impact on the reaction process and the purity of the product. Through careful adjustment, the reaction is promoted to proceed smoothly and another important intermediate is formed.
At the end of the final step, a specific carboxylation reaction is applied to the obtained intermediate. Select the appropriate carboxylation reagent and introduce the carboxyl group at the target check point under suitable reaction conditions, resulting in 4- (9H-xanthon-9-yloxycarbonyl amino) -1-methyl-1H-pyrazole-2-carboxylic acid. The purity and yield of this product are related to the precise control of each step of the reaction. From the balance of material ratio to the determination of reaction time, it is necessary to be careful in order to achieve the desired synthetic effect.

4- (9H-Tie-9-methoxycarbonyl-oxy-carbonyl) -1-methyl-1H-pyrrole-2-carboxylic acid is an organic compound, and its storage conditions are not directly recorded in Tiangong Kaiwu, but it can be deduced from the wisdom of the ancients on the preservation of similar substances and modern chemical knowledge.
Ancient collection, heavy dry, cool, and protected from light. For these things, a dry environment is essential. Because it contains many groups that are easy to react with water, if the environment is humid, water molecules are easy to attack, causing structural changes and property changes. Such as ancient medicine, often placed in a lime tank to absorb moisture, this thing may be similar, choose a sealed container, put desiccant inside, to prevent moisture dissolution.
In a cool place, avoid high temperature. High temperature can increase molecular activity, promote the decomposition of this compound or cause side reactions. There is a method of hiding ice in ancient times, and it is difficult to reduce room temperature in summer. Although it is difficult to use this thing for large-scale storage, it can be used. Choose a cool warehouse and control the room temperature within an appropriate range.
Avoid light and do not ignore it. Light is energy, which can cause photochemical reactions, which can break chemical bonds and change the structure of this compound. Ancient people used cloth to cover windows and protect them from light. This thing may be stored in dark containers such as brown bottles to reduce the effect of light. < Br >
In addition, anti-oxidation is also crucial. There are oxidizable parts in its structure, which should be stored in oxygen isolation. The ancient oil sealing method used oil to isolate the air, but now it can be protected by inert gas. Nitrogen and other gases are filled in the storage container to prevent it from connecting with oxygen, ensuring its chemical properties are stable and achieving good storage effect.
