The synthesis of 1 - [3 - [ (2,5 -pyridyl dioxide) oxy] aldehyde] benzyl] -1H -pyridine-2,5 -dicarboxylic acid is a key topic in the field of organic synthetic chemistry. Although the specific synthesis method is not described in Tiangong Kaizi, according to the conventional ideas and traditional chemical wisdom of today's organic synthesis, it may be discussed according to the following ancient ideas.
To synthesize this substance, the selection of starting materials is crucial. Or pyridine derivatives can be selected as the basic raw materials, because their structure is partially compatible with the target product pyridine ring. First, the 2,5-position of the pyridine ring is modified. Pyridine can be introduced into the halogen atom at the 2,5-position by a halogenation reaction, such as bromine with a suitable catalyst, such as iron powder, and pyridine under heating conditions to bromide at the 2,5-position to obtain 2,5-dibromopyridine.
Subsequently, 2,5-dibromopyridine is reacted with an oxygen-containing reagent. For example, by reacting with a sodium alcohol reagent, nucleophilic substitution, the oxygen group is introduced at the 2,5-position to obtain a 2,5-pyridine dioxide derivative. On the basis of this derivative, the aldehyde group is attached to the pyridine ring. The derivatives can be treated by a Vilsmeier-Haack reaction with a mixture of N, N-dimethylformamide (DMF) and phosphorus oxychloride (POCl
As for the introduction of the benzyl part, the aldehyde-containing pyridine derivative can be reacted with benzyl halide, such as benzyl bromide, under basic conditions by Williamson ether synthesis. The base can be selected from potassium carbonate, etc., heated and refluxed in a suitable organic solvent such as acetone, so that the two are connected to obtain a benzyl-containing pyridine derivative.
Finally, the carboxylation reaction is carried out for the 2,5-position of the pyridine ring. The above derivatives can be reacted with carbon dioxide at low temperature in anhydrous ether and other solvents through Grignard reagent intermediates, and finally carboxylated to produce the target product 1 - [3- [ (2,5-pyridyl dioxide) oxy] aldehyde] benzyl] -1H-pyridine-2,5-dicarboxylic acid. Each step of the reaction requires precise control of the reaction conditions, including temperature, time, reagent dosage, etc., to achieve the ideal yield and purity.

Looking at its properties, it is mostly solid under normal conditions, but the specific form may vary depending on the purity and preparation conditions.
When it comes to melting point, there is no exact universal value. Due to differences in different literature reports or experimental conditions, the melting point data will fluctuate. But generally speaking, within a certain temperature range, when heated to this temperature range, the substance gradually melts from a solid state to a liquid state. The boiling point of
also varies depending on the experimental measurement conditions. However, usually at higher temperatures, it will change from liquid to gaseous state, and the temperature required for this process is the boiling point.
In terms of solubility, in organic solvents, such as common ethanol and dichloromethane, it has a certain solubility. This characteristic is due to the specific interaction between its molecular structure and the molecules of the organic solvent, so that the molecules can be uniformly dispersed in the solvent. However, in water, the solubility is poor, because the polarity of the molecule and the polarity of the water molecule are not well matched, and it is difficult for the water molecule to effectively disperse and surround the substance molecules. < Br >
