There are many ways to synthesize methyl 2-ethoxy-3H-benzo [d] imidazole-4-carboxylate.
First, we can start from the starting material containing benzene ring and imidazole structure. The ethoxy group is introduced at a specific position of the benzene ring first, which can be achieved by nucleophilic substitution reaction. For example, a benzene derivative containing a halogen atom reacts with sodium ethanol, and the halogen atom is replaced by ethoxy to obtain an ethoxylated benzene derivative. Then, the imidazole ring is constructed through a series of reactions, which can be condensed with compounds containing functional groups such as carbonyl and amino groups by suitable nitrogen-containing reagents to form an imidazole ring structure. Finally, the carboxyl group is introduced at the 4th position of the imidazole ring and converted into a methyl ester group. Carboxylation reagents can be used, and then esterification reaction can be carried out with methanol.
Second, benzimidazole can also be used as the base material. First, the second position of benzimidazole is ethoxylated, and a suitable halogenated ethane can be used to react with benzimidazole under base catalysis to achieve the introduction of ethoxy groups. After that, the carboxyl group is introduced at the 4th position, which can be reacted with benzimidazole by means of a specific carboxylation reagent, such as carbon dioxide under the action of a suitable metal catalyst and base. Finally, the carboxyl group is converted into methyl ester group, and the esterification reaction is carried out with methanol and catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid, to obtain the target product methyl 2-ethoxy-3H-benzo [d] imidazole-4-carboxylate.
During the synthesis process, attention should be paid to the precise control of the reaction conditions, such as temperature, pH, reaction time, etc., and the products should be carefully separated and purified at each step to improve the purity and yield of the target product.

The physical and chemical properties of methyl 2-ethoxy-3H-benzo [d] imidazole-4-carboxylic acid esters are as follows.
Looking at its properties, it is mostly in a solid state at room temperature, and the texture is or is crystalline. Due to the interaction between molecular structures, the molecules are arranged in an orderly manner, so it has this shape.
When it comes to solubility, it may have a certain solubility in organic solvents such as ethanol and acetone. This is because the molecules of the compound and the organic solvent molecules can form interactions such as van der Waals force and hydrogen bonds, so that it can be dispersed in the solvent. However, in water, its solubility is not good, because the hydrophobic groups in the molecule account for a large proportion, it is difficult to form an effective affinity with water molecules, and the polarity of water does not match the molecular polarity of the compound.
Its melting point is also an important physical property. When heated to a specific temperature, the molecule obtains enough energy, the lattice structure begins to disintegrate, and then the transition from solid to liquid occurs. This temperature is the melting point. The melting point depends on the strength of the intermolecular forces, including hydrogen bonds, van der Waals forces, etc. If the intermolecular hydrogen bonds of the compound are many and strong, or the van der Waals force is large, the melting point is higher; vice versa.
In terms of chemical properties, its molecules contain ester groups, which are common to esters. In case of alkali, hydrolysis reaction can occur. The alkali attacks the carbonyl carbon in the ester group, causing the ester bond to break and forming the corresponding carboxylate and alcohol. In case of sodium hydroxide solution, it can be hydrolyzed into 2-ethoxy-3H-benzo [d] imidazole-4-carboxylic acid sodium salt and ethanol. At the same time, the benzimidazole ring also has certain reactivity. The nitrogen atom on the ring can participate in the nucleophilic reaction. Because the nitrogen atom has lone pairs of electrons, it can be used as a nucleophilic reagent to attack suitable electrophilic reagents, and reactions such as alkylation and acylation can occur. Structural modification and derivatization can be carried out according to this characteristic in organic synthesis.

The price of methyl 2-ethoxy-3H-benzo [d] imidazole-4-carboxylic acid ester in the market is difficult to determine. This compound is not commonly available, and its price is not listed in ancient books such as Tiangong Kaiwu.
In today's chemical market, prices often change due to many reasons. First, the price of raw materials fluctuates. If the raw materials required to synthesize this ester are rare or expensive, the price of the finished product will also be high. Second, the difficulty of preparation has a great impact. If the synthesis steps are complicated and special equipment and technology are required, the cost will increase, and the price will also rise. Third, the relationship between supply and demand in the market is crucial. If there are many buyers and few suppliers, the price will be high; on the contrary, if the supply exceeds the demand, the price may drop.
And in different merchants and regions, the price also varies. Professional chemical raw material suppliers may be able to supply them at a lower price due to large purchases and excellent channels; while small-scale distributors may have slightly higher prices. Furthermore, domestic and foreign markets have different prices due to tariffs, transportation costs, etc.
Therefore, to know the exact price, you need to consult chemical raw material suppliers and trading platforms, and study the market conditions in detail to obtain a more accurate number.
