To prepare 6% 2C7-diethoxy-1% 2C2% 2C3% 2C4-tetrahydroisoquinoline benzoate, the method is as follows:
First, take an appropriate amount of starting materials and convert them through multiple delicate reactions. The first step is to select the appropriate substrate and use specific reagents and conditions to promote the reaction. This step aims to build the skeleton structure of the foundation. During the reaction, it is necessary to precisely control the temperature and time to make the reaction proceed smoothly. If the temperature is too high or the time is too long, it may cause side reactions to increase, which will affect the purity and yield of the product.
Next, modify the initial product and add diethoxy groups. The reagents used in this process must be pure, and the reaction environment should be anhydrous and oxygen-free. Because of the strict environmental requirements of this type of reaction, a little carelessness will fall short.
Then, through a series of reactions, the structural part of tetrahydroisoquinoline is gradually introduced. Each step requires fine operation, paying attention to the purity of the reaction process and intermediate products.
After the basic structure is formed, the last step is to esterify the structure with benzoic acid to obtain 6% 2C7-diethoxy-1% 2C2% 2C3% 2C4-tetrahydroisoquinoline benzoate. In this esterification reaction, the choice and dosage of catalysts are crucial, which can accelerate the reaction process and improve the yield. At the same time, after the reaction is completed, it needs to go through separation, purification and other processes to obtain a high-purity target product.
The entire preparation process is like a delicate chemical dance, and every step needs to be orchestrated and precisely controlled by chemists to achieve the desired preparation effect.

6,7-Diethoxy-1,2,3,4-tetrahydroisoquinoline benzoate should be carefully controlled during storage and transportation, as follows:
First, the control of temperature and humidity. This compound is quite sensitive to temperature and humidity. High temperature can easily cause its chemical structure to mutate and reduce its activity; if the humidity is too high, it may cause deliquescence and damage its quality. Therefore, storage should be in a cool and dry place. The temperature is preferably 15-25 degrees Celsius, and the relative humidity should be controlled at 40% -60%. When transporting, it is also necessary to ensure that the ambient temperature and humidity are stable. Temperature-controlled transportation equipment can be used to prevent sudden changes in temperature and humidity during transportation.
Second, avoid light. The substance is sensitive to light. Long-term light or strong light can cause it to undergo photochemical reactions and cause changes in its composition. Storage should be in opaque containers, such as brown glass bottles. When transporting, shading measures should also be taken, such as covering with a shading cloth.
Third, to prevent vibration and collision. Its physical form may change due to vibration and collision, which affects the quality. During transportation, choose a smooth transportation tool and fix it properly to avoid severe bumps. When storing, handle it lightly to prevent it from falling from a height.
Fourth, store it in isolation. 6,7-diethoxy-1,2,3,4-tetrahydroisoquinoline benzoate cannot be stored and transported together with oxidizing, reducing substances and acids and alkalis. Due to its active chemical properties, contact with the above substances is prone to chemical reactions, or risk of combustion, explosion, etc.
Fifth, the identification is clear. On storage containers and transportation packaging, its name, nature, danger warning and other information should be clearly marked. So that relevant personnel can identify, follow safety procedures during operation, and quickly grasp key information during emergency response.
