The method of preparing 3-chloro-6-methoxy-1-benzothiophene-2-carboxylic acid can be carried out according to the following steps.
In the first step, select a suitable starting material, such as 6-methoxy-1-benzothiophene-2-carboxylic acid, which is the reaction base. Place it in a suitable reaction vessel, which should be clean and dry to avoid impurities disturbing the reaction.
In the second step, introduce a chlorinated reagent. Commonly used ones are sulfoxide chloride, phosphorus oxychloride, etc. Taking thionyl chloride as an example, under low temperature and stirring conditions, thionyl chloride is slowly added dropwise to the reaction system containing 6-methoxy-1-benzothiophene-2-carboxylic acid. The reaction rate is controlled at low temperature to prevent the growth of side reactions; stirring promotes the uniform mixing of raw materials and reagents to make the reaction sufficient. This process requires close monitoring of the reaction temperature and system changes.
When the chlorination reagent is added, gradually raise the temperature to a suitable reaction temperature and maintain it for a certain period of time. The temperature and time depend on the specific conditions of the reaction, usually reacting under moderate heating conditions for several hours. During the process, the raw material 6-methoxy-1-benzothiophene-2-carboxylic acid is chemically reacted with the chlorination reagent and gradually converted into the target product 3-chloro-6-methoxy-1-benzothiophene-2-carboxylic acid.
After the reaction is completed, the product needs to be separated and purified. It can be extracted with a suitable solvent to preliminarily separate the product from the impurities in the reaction system. Then it can be further purified by recrystallization, column chromatography, etc., to obtain high-purity 3-chloro-6-methoxy-1-benzothiophene-2-carboxylic acid. During recrystallization, a suitable solvent is selected to dissolve the product at high temperature and precipitate at low temperature to remove impurities; column chromatography achieves separation according to the difference in the partition coefficient between the product and impurities in the stationary phase and the mobile phase.
In this way, 3-chloro-6-methoxy-1-benzothiophene-2-carboxylic acid can be obtained through the steps of raw material selection, chlorination reaction, product separation and purification, etc. However, in actual operation, the reaction parameters and steps must be fine-tuned according to specific experimental conditions and requirements to achieve the best preparation effect.

I don't know the price range of "3-chloro-6-methoxy-1-benzothiophene-2-carboxylic acid" in the market. This is a rather professional chemical, and its price is often influenced by many factors.
First, purity is the key factor. If the purity is extremely high, it is almost used for high standards of scientific research, and the price will be high. Because the purification process is complicated, it consumes a lot of manpower, material resources and time. Second, market supply and demand also have an impact. If the demand for it increases sharply at a certain time, if the pharmaceutical industry is in urgent need of developing new drugs, and the supply is limited, the price will rise; conversely, if the supply exceeds the demand, the price may decline. Third, the production scale is also related to the price. Large-scale production, the cost may be dilutive, and the price may be more affordable; small-scale production, the unit cost is high, and the price is also high.
In addition, the relevant market information of this substance may be difficult to find because it is not a common bulk chemical. Or it needs to be explored on professional chemical raw material trading platforms and chemical product suppliers, and the quotations of different regions and different suppliers may vary. Or you can contact relevant chemical companies and chemical reagent companies to inquire for a more accurate price range.
