To prepare 1- [ (3,4-diethoxybenzyl) acetyl] -6,7-diethoxy-1,2,3,4-tetrahydroisoquinoline, the following methods can be used:
First, start with 3,4-diethoxyphenylacetonitrile, first reduce to obtain 3,4-diethoxyphenethylamine, and then condensate with acetyl chloride to obtain amide, and then Bischler-Napieralski cyclization, reduction and other series of reactions. The raw materials are easy to obtain, but the steps are complicated, and multi-step reaction and separation are required, which requires high operating skills. < Br >
Second, it is condensed with ethyl acetoacetate based on 3,4-diethoxy benzaldehyde, and then reduced and cyclized. The steps of this method are slightly simplified, but the condensation reaction conditions are strict, and precise temperature control and reagent ratio are required to improve the yield and purity.
Third, 3,4-diethoxy benzyl chloride and acetylacetone are used as the starting point. First condensation, and then cyclization and reduction reactions are used to obtain the target product.

1-% 5B% 283% 2C4-diethoxybenzyl% 29 acetyl% 5D-6% 2C7-diethoxy-1% 2C2% 2C3% 2C4-tetrahydroisoquinoline, this is an organic compound. Its physical and chemical properties are quite important, which is related to its application in many fields.
Looking at its physical properties, under normal conditions, it is either a solid or a viscous liquid, depending on the intermolecular force and crystallinity. Its melting point and boiling point are key parameters. The melting point characterizes the temperature at which a substance changes from a solid state to a liquid state, and the boiling point is the temperature at which the liquid state changes to a gas state. The melting point and boiling point values of this compound are closely related to its molecular structure. The stronger the intermolecular force, the higher the melting point and boiling point. The presence of substituents such as diethoxy will change the intermolecular force, which in turn affects the melting boiling point.
Solubility is also an important physical property. In organic solvents, such as ethanol, acetone, etc., or have good solubility, due to the principle of similar phase solubility, its organic structure is similar to that of organic solvents. However, in water, its solubility or poor, because its non-polar part is large, and its polarity is different from that of water.
Chemically, it has certain reactivity. Substituents on the benzene ring, such as diethoxy, can participate in electrophilic substitution reactions. Benzyl and acetyl moiety, or can undergo oxidation and reduction reactions. Its nitrogen atom, due to its lone pair of electrons, or can participate in the reaction as a nucleophilic reagent, exhibits alkalinity and reacts with acids to form salts.
In chemical reactions, its structure can be modified and modified through specific reaction conditions to meet different chemical synthesis needs. In the field of organic synthesis, or as an important intermediate, it is converted into more complex organic compounds with specific functions through a series of reactions.

I don't know what you mean by "1-%5B%283%2C4-%E4%BA%8C%E4%B9%99%E6%B0%A7%E5%9F%BA%E8%8B%AF%E5%9F%BA%29%E4%BA%9A%E7%94%B2%E5%9F%BA%5D-6%2C7-%E4%BA%8C%E4%B9%99%E6%B0%A7%E5%9F%BA-1%2C2%2C3%2C4-%E5%9B%9B%E6%B0%A2%E5%BC%82%E5%96%B9%E5%95%89". This expression seems to contain many uncommon chemical terms and symbols. However, it is difficult for me to understand the exact meaning of the price relationship between its combination and market conditions.
The prices of various things in the city often change with supply and demand, the current situation, and the cost of labor. If you want to know the exact market price of something, you should look at the merchants in the city, or ask people in the industry who are familiar with the market. Or look at the records of past transactions to deduce the trend of its price. However, I have not known the quality, use, and production and sales of the things you mentioned. It is difficult to determine the price of them in the market.
If this item is rare, or traded in a specific domain or at a specific time, its price is even more difficult to predict. It is necessary to carefully consider the situation and the matter involved before it can be expected to know its approximate price.
