Then, the carboxyl group is introduced at the 2-position of the thiophene ring. The 2-position can be halogenated by halogenation reaction, and then replaced by cyanyl group, and then hydrolyzed to convert into carboxyl group. Suitable halogenating reagents can be selected for halogenation reaction, such as N-bromosuccinimide (NBS). Cyanyl substitution uses the reaction of halides with cyanide reagents. The hydrolysis step is usually carried out under acidic or basic conditions, depending on the specific reaction conditions.
Furthermore, the amino group is introduced at the 3-position. Nitro groups can be introduced first, and then reduced to amino groups through nitration reaction. Nitrification is usually done in a mixed acid system of nitric acid and sulfuric acid to nitrate the thiophene ring at the 3-position. There are many ways to reduce nitro groups. The common ones are reduction of metals such as iron powder and zinc powder in an acidic medium, or catalytic hydrogenation. Using palladium carbon as a catalyst and hydrogen as a reducing agent, the nitro group is smoothly converted into an amino group, and then 3-amino-5-phenylthiophene-2-carboxylic acid is obtained.
These methods are all based on the principles of organic chemistry. Due to the different factors such as reaction conditions, availability of raw materials and yield, the purpose of synthesis can be achieved by selecting them.
