Method for preparing (8Z) -8- {4 '- [ (E) - (4-ethoxybenzyl) diazo] bibenzyl-4-yl} naphthyl-7-oxidized-7,8-dihydrophenanthrene-1,3-diacid
To obtain (8Z) -8- {4' - [ (E) - (4-ethoxybenzyl) diazo] bibenzyl-4-yl} naphthyl-7-oxidized-7,8-dihydrophenanthrene-1,3 - Diacid can be prepared according to the following steps:
Prepare starting materials
Select suitable 4-ethoxy benzyl compounds, bibenzyl derivatives and naphthyl-related raw materials to ensure the purity and quality of raw materials. This is the basis for the reaction. If the raw materials are not good, the product will be difficult to form.
Diazo group is introduced into the reaction
in a suitable reaction vessel. After the 4-ethoxy benzyl compound is properly treated, under specific reaction conditions, such as low temperature, the presence of a catalyst, etc., diazo groups are introduced to form (E) - (4-ethoxy benzyl) diazo intermediates. This step requires precise control of the reaction conditions. If the temperature is too high or the amount of catalyst is improper, it is easy to cause the decomposition of diazo groups or the deviation
Bibenzyl Linking Reaction
Mix the above diazo-containing intermediate with bibenzyl derivative, react under suitable solvent and reaction conditions, so that the diazo group is connected to the specific position of bibenzyl to generate 4 '- [ (E) - (4-ethoxybenzyl) diazo] bibenzyl-4-yl structure. This step requires attention to the reactivity and selectivity to ensure the accurate connection position.
with naphthyl group and subsequent cyclization and oxidation reaction
The formed 4 '- [ (E) - (4' ethoxybenzyl) diazo] bibenzyl-4 '-group structure was preliminarily constructed with naphthyl group through a series of reactions such as condensation and cyclization under suitable reaction conditions. Subsequently, the oxidation step is carried out, the oxidation group is introduced at the 7 position, and the dihydrogen structure is constructed at the 7 and 8 positions. Finally, the 1,3-diacid structure is obtained through post-processing steps such as acidification, and the target product (8Z) -8- {4 '- [ (E) - (4-ethoxybenzyl) diazo] benzyl-4-yl} naphthyl-7-oxidized-7,8-dihydrophenanthrene-1,3-diacid is prepared.
After the reaction is completed, it needs to be separated and purified, such as column chromatography, recrystallization, etc., to remove impurities and obtain high-purity products. The entire preparation process requires strict control of the reaction conditions and precise operation in order to obtain the target product stably and efficiently.

(8Z) -8- {4 '- [ (E) - (4-ethyloxyphenyl) diazophenyl] biphenyl-4-yl} naphthyl-7-oxo-7,8-dihydropteridine-1,3-dione, this substance has the following physical and chemical properties:
In terms of appearance, it often appears in solid form, and the specific color may vary depending on the purity and crystallization state. Generally, it is mostly white to light yellow powdery solid. This is due to the conjugate system in its molecular structure and the nature of the substituent. The conjugate system will absorb and reflect light to a certain extent, thus affecting its appearance and color.
In terms of solubility, it has a certain solubility in common organic solvents such as dichloromethane and chloroform. This is due to the fact that there is a certain hydrophobic part in its molecular structure, which can interact with organic solvent molecules through van der Waals forces to promote their dissolution. However, the solubility in water is poor because water molecules have strong polarity, while the overall polarity of the substance is relatively weak, and it is difficult to form an effective interaction with water molecules, so it is not easily soluble in water.
In terms of stability, the substance has good stability under the conditions of normal temperature, pressure and protection from light. However, when it is in a high temperature environment, the vibration of chemical bonds within the molecule intensifies, which may lead to the breakage of some chemical bonds, which may lead to decomposition reactions. At the same time, if exposed to strong light, especially ultraviolet radiation, the conjugated system in the molecule may absorb photon energy, undergo photochemical reactions, and cause its structure to change.
The melting point range is usually in a specific range, which depends on the force between molecules. Intermolecular interactions such as van der Waals forces and hydrogen bonds jointly determine its melting point. Accurate melting point values are of great significance for the purity identification of the substance. The higher the purity, the closer the melting point is to the theoretical value, and the narrower the melting range.
In terms of chemical reactivity, because its molecular structure contains diazophenyl, naphthyl, pteridine dione and other functional groups, it has unique reactivity. Diazophenyl can participate in a variety of coupling reactions. It acts as an important reaction check point in organic synthesis. It reacts with compounds containing active hydrogen to construct new carbon-carbon or carbon-heteroatom bonds. Naphthyl is prone to electrophilic substitution due to its conjugate structure. Under appropriate reaction conditions, various substituents can be introduced to further modify the molecule. The carbonyl group in the structure of pteridine dione has certain electrophilicity and can react with nucleophiles, so as to realize the structural modification and derivatization of the substance.

I think your question is about (8Z) -8- {4′ - [ (E) - (4-ethoxyphenyl) diazo] biphenyl-4-yl} naphthyl-7-oxidized-7,8-dihydrophenanthrene-1,3-dicarboxylic acid whether there is a safety risk. This is a question related to fine chemicals, which is related to the characteristics and hazards of things.
In the context of "Tiangong Kaiwu", although there is no such fine analysis method as modern chemistry, it can be inferred by its observation of things. Everything in the world has its own nature. This chemical substance, according to its name, has a complex structure and complex chemical properties.
Any chemical substance should be treated with caution. When synthesizing, the materials used may be toxic and dangerous to ignition and explosion. If the synthesis method is not handled properly, it will also cause disasters.
Also consider the use of this substance. If it involves medical drugs, food and other human-related fields, safety risks need to be carefully observed. Because of its contact with the human body, a little carelessness can endanger health.
If it is used in industrial production, its discharge and storage are also important. If the discharge is not in accordance with the law, it will pollute the environment and harm all living beings; if it is not properly stored, if it encounters disasters such as water and fire, it may leak and cause harm to all directions.
Although there is no conclusive evidence as to whether it is safe or not, it is common sense that such complex chemical substances must be investigated in detail, following scientific laws and strict regulations, testing their properties and observing their risks, and then judging whether there are any hidden dangers in a safe environment. It must not be dealt with rashly, so as not to cause unexpected disasters.
