To prepare pentylenebis [1- (3,4-dimethoxybenzyl) -3,4-dihydro-6,7-dimethoxy-1H-isoquinoline-2-propionate] dioxalate, the method is as follows:
First, all raw materials need to be prepared, such as 3,4-dimethoxybenzaldehyde, 1,5-pentanediol, 6,7-dimethoxy-3,4-dihydroisoquinoline, etc., and the required reagents and solvents, such as acids, bases, organic solvents and the like. < Br > First take 3,4-dimethoxy benzaldehyde and 6,7-dimethoxy-3,4-dihydroisoquinoline, in an organic solvent in an appropriate ratio, catalyze with a specific catalyst to control the temperature to initiate a condensation reaction. When reacting, pay close attention to changes in temperature and reaction time, and wait for the reaction to reach the desired degree to obtain an intermediate product.
The 1,5-pentanediol and the obtained intermediate product are combined in another reaction system in an appropriate ratio, and a specific reaction reagent is added to make the two esterified under appropriate conditions. This process also requires careful control of reaction conditions, such as temperature, pH, etc., to promote the smooth progress of the reaction and obtain a product containing pentylene methylene structure. After
, oxalic acid and the above product are carried out in a specific solvent in a certain proportion to form a salt. After carefully adjusting the reaction conditions, pentylene methyl bis [1- (3,4-dimethoxybenzyl) -3,4-dihydro-6,7-dimethoxy-1H-isoquinoline-2-propionate] dioxalate is formed.
After the reaction is completed, the product is separated and purified, and its impurities can be removed by filtration, extraction, recrystallization and other methods to obtain a pure product. The whole preparation process requires strict compliance with the operating procedures and precise control of various reaction parameters to obtain satisfactory results.

When using this utensil, all the precautions must be kept in mind.
First, check its shape and quality. Examine the shape and texture of the utensil carefully before use. See if it is damaged or cracked. If there are flaws, it may be hindered during use or cause accidental changes. For example, a crossbow, if the string looks like a broken strand, when the arrow is fired, it may cause the bow to break and go astray, hurting people and causing mistakes.
Second, understand its usage. Each thing has its own unique use, and it should be familiar with it. For example, the ancient crossbow, including the method of operation, all have rules. If you don't know its law and move rashly, you will not be able to make the best use of it, but it will be vulnerable. And if the equipment used in the armor of the Qimen is complicated to use, the difference is the slightest, and the fallacy is thousands of miles, so you can't be careless.
Third, choose its timing. When using things, the right time is also important. The weather, the location, and the people should all be considered. For example, if a catapult is used in a battle formation, if the rain and the road are slippery, the stone is difficult to send far and easy to deviate, and it must wait for the sunny day and the road to dry before it can exert its power. Another example is a diplomatic ceremonial weapon, which is used at an inappropriate time, or it may cause misunderstanding and bad friendship.
Fourth, nourish the utensils. After use, it should be properly maintained to prolong its life. After the sword is used, wipe it with an oil cloth and hide it in a dry place to Wooden ware needs to be protected from moisture and moisture to prevent it from spoiling. If it is not properly cared for, the lifespan of the utensils will be short, and it will be difficult to use it next time.
Fifth, to prevent its drawbacks. Any utensils have advantages and disadvantages. For example, although firearms are powerful, they are easy to go off and inconvenient to handle. When using them, they must be prevented from exploding, properly placed, and handled with caution. Do not forget their disadvantages because of their advantages.
In general, when using this object, you should pay careful attention to the shape, usage, timing, maintenance, drawbacks, etc., so that you can make the best use of it and be safe.
