To prepare 1- (3,4-dimethoxybenzyl) -6,7-dimethoxy-3,4-dihydroisoquinoline benzoate, the method is as follows:
First take an appropriate amount of 3,4-dihydroxybenzaldehyde, place it in a clean reaction vessel, and use an appropriate amount of dimethyl sulfate as a methylating agent to react in an alkaline environment. The alkaline environment can be provided by alkaline substances such as potassium carbonate, and the reaction temperature should be controlled in a moderate range, such as between 40 and 60 degrees Celsius, and continue to stir for several hours to make the reaction fully proceed to obtain 3,4-dimethoxybenzaldehyde.
Mix the prepared 3,4-dimethoxybenzaldehyde with an appropriate amount of nitromethane, add a little piperidine as a catalyst, and react for a period of time at a suitable temperature, such as between 60 and 80 degrees Celsius. After the reaction is completed, the separation and purification method can obtain 3- (3,4-dimethoxyphenyl) -2-nitropropene.
Take 3- (3,4-dimethoxyphenyl) -2-nitropropene and carry out the reduction reaction with a suitable reducing agent, such as iron powder and a reduction system composed of hydrochloric acid. During the reaction, pay attention to control the reaction temperature and the amount of reducing agent, so that the nitro group is reduced to an amino group to obtain 3- (3,4-dimethoxyphenyl) propylamine.
Mix 3- (3,4-dimethoxyphenyl) propylamine with an appropriate amount of 2,3-dimethoxybenzoyl chloride, add an appropriate amount of acid binding agent, such as triethylamine, in an inert solvent, such as dichloromethane, under low temperature conditions, such as 0 to 5 degrees Celsius, stir the reaction for a period of time, then warm up to room temperature, and continue the reaction for several hours to obtain 1 - (3,4-dimethoxybenzyl) -6,7-dimethoxy-3,4-dihydroisoquinoline.
Finally, 1 - (3,4 - dimethoxybenzyl) - 6,7 - dimethoxy - 3,4 - dihydroisoquinoline is mixed with an appropriate amount of benzoic anhydride, anhydrous aluminum trichloride as a catalyst, in a suitable organic solvent, such as dichloroethane, heated and refluxed. After the reaction is completed, the target product 1 - (3,4 - dimethoxybenzyl) - 6,7 - dimethoxy - 3,4 - dihydroisoquinoline benzoate can be obtained through a series of separation and purification operations, such as extraction and column chromatography. The whole process requires attention to the precise control of the reaction conditions, and the separation and purification of the products in each step is also crucial, so as to make the product pure and achieve the desired purpose.

The question asked by the observer is related to the market price of 1- (3,4-diaminocarbonyl) -6,7-diamino-3,4-dihydro isosanhydride. This compound may have specific uses in various chemical and pharmaceutical fields.
However, it is not easy to understand its market price. The price of its cover often varies due to many factors. First and foremost, the price of raw materials. If the various raw materials required for the synthesis of this compound are abundant and affordable, the cost of the product may be reduced, and the price will also be lower. On the contrary, raw materials are scarce and expensive, and products must be expensive.
Furthermore, the art of production also has an impact. An efficient production process can reduce consumption and improve quality, reduce costs and promote price stability. If the process is difficult, the loss is large and the output is small, the price will be high.
The supply and demand of the market is particularly critical. If the market demand for this product is strong and the supply is limited, the merchant will raise the price to make a profit. On the contrary, if the demand is low and the stock is large, the price will fall.
In addition, regional differences and policy regulations can affect the price. In different places, due to differences in logistics and taxes, the price may be different. If the policy supports the relevant industries, it will also cause price changes.
In summary, in order to determine the exact market price of 1 - (3,4 - diaminocarbonyl) -6,7 - diamino- 3,4 - dihydro isosanhydride, it is necessary to gather extensive industry information, observe the price of raw materials, process progress, supply and demand conditions, and geographical and policy influences, in order to obtain relatively accurate numbers.

1 - (3,4 -diaminoethoxy phenyl) -6,7 -diethoxy-3,4 -dihydroisoquinoline carboxylate should pay attention to the following matters during storage and transportation:
First, this substance is quite sensitive to temperature. High temperature can easily cause its chemical structure to change, or cause decomposition and deterioration, which in turn affects its quality and utility. Therefore, when storing, it should be placed in a cool place, the temperature should be controlled within a specific range, and it must not be stored in a high temperature environment. For example, it should not be stored in a car with direct sunlight in summer.
Second, humidity will also affect it. High humidity environment can easily make the substance damp, which may cause it to agglomerate and even chemically react. Therefore, the storage place must be kept dry, and the environment can be maintained in a dry state with the help of desiccants.
Third, it is necessary to ensure that the packaging is intact during transportation. This substance has certain chemical activity. If the packaging is damaged, it may react in contact with external substances, which will not only endanger the safety of transportation, but also lose itself. Packaging with good sealing and suitable materials should be selected, such as sturdy glass bottles sealed with wax, or specific plastic materials, and shock-proof and extrusion-proof measures should be taken to prevent damage to the packaging during transportation.
Fourth, it is necessary to avoid coexistence with oxidizing substances and reducing substances. Due to its special chemical properties, contact with oxidizing or reducing substances is prone to severe chemical reactions, or serious consequences such as combustion and explosion. During storage and transportation, it is necessary to isolate such substances.
Fifth, fireworks should be strictly prohibited in storage and transportation places. This substance may be flammable, and may cause combustion in case of open flames and hot topics, threatening personnel safety and the environment. Relevant fire safety regulations must be strictly followed and necessary fire protection equipment must be equipped.
