A method for the synthesis of 5-acetylthiophene-2-carboxylic acid esters.
The first method is to use thiophene-2-carboxylic acid ester as the starting material. First, it is reacted with an acetylating agent, such as acetyl chloride or acetic anhydride, in the presence of a suitable catalyst. The commonly used catalyst is Lewis acid, such as anhydrous aluminum trichloride. This reaction starts at a low temperature, such as between 0 and 10 ° C, and then gradually heats up to room temperature or slightly higher, such as 20-30 ° C. After continuous stirring for several times, depending on the reaction process, or several or even ten hours, through this step, the 5-position thiophene ring can be introduced into the acetyl group to obtain the target product 5-acetylthiophene-2-carboxylic acid ester. After the reaction is completed, the product can be purified by conventional separation methods, such as extraction, column chromatography, etc.
There is another method to acetylate thiophene first. Using thiophene as raw material and reacting with acetylation reagents under suitable conditions, 5-acetylthiophene is obtained. After that, 5-acetylthiophene is reacted with carboxylating reagents, such as carbon dioxide, at a low temperature, such as -78 ° C, in the presence of strong bases, such as n-butyl lithium and suitable solvents, and then hydrolyzed at temperature. The 2-position of 5-acetylthiophene can be introduced into the carboxyl group, and then esterified with alcohols under acid catalysis to obtain 5-acetylthiophene-2-carboxylic acid ester. After the reaction is completed, the products need to be purified by extraction, distillation, recrystallization, etc., to obtain pure target compounds.

I have not seen the exact price of 5-acetylthiophene-2-carboxylate in the market. This is a fine chemical product, and its price often varies according to quality, quantity, supply and demand, manufacturing process and market conditions.
If the quality is high and pure, it reaches a high purity standard, and is suitable for high-end scientific research, pharmaceutical and other industries, its price may be high. And the amount is also the main reason. If the purchase quantity is huge, the merchant may offer a discount, and the unit price may drop; if the purchase quantity is small, the price may be relatively high.
The state of supply and demand also affects its price. If there are many people in demand, and the supply is limited, the price may rise; if the supply exceeds the demand, the price may decline. Furthermore, the complexity of the preparation process is related to the cost. If the process is complicated, time-consuming, and multiple materials are used, the cost will increase and the price will be high.
In the market, it is difficult to determine an exact price range because different merchants have different pricing and the market is constantly changing. To know the actual price, it is advisable to consult chemical raw material suppliers, reagent sellers, or investigate on chemical trading platforms and professional markets to obtain a timely and accurate price.
