The synthesis method of 4-methoxy-2-aminobenzothiazole has existed in ancient times, and it has evolved over time.
In the past, o-methoxy aniline was often used as the starting material, and it was first reacted with ammonium thiocyanate to generate the corresponding thiourea derivative. This reaction needs to be carried out in a specific temperature and solvent environment, such as in an organic solvent such as ethanol, and the temperature is slowly heated to promote the smooth occurrence of the reaction. After the thiourea derivative is formed, it is cyclized under acidic conditions, mostly with strong acids such as concentrated sulfuric acid as the catalyst. After the cyclization process, 4-methoxy-2-aminobenzothiazole is finally obtained. However, although this ancient method can achieve the synthesis of the target product, there are many drawbacks. The use of strong acids is very corrosive to the reaction equipment, and the reaction conditions are harsh. If the operation is slightly careless, it is easy to cause low yield or generate many by-products.
Later scholars found another way to solve this dilemma. Using 2-halo-4-methoxyaniline as raw material, it reacts with sulfides. Among the sulfides, common reagents such as sodium sulfide can be selected. The reaction can occur under relatively mild conditions, without strong acid catalysis, and the requirements for the reaction equipment are not as harsh as in the past. Under the action of appropriate alkali catalysis, the two can react smoothly and obtain the target product through cyclization. This new method not only simplifies the operation process, but also greatly improves the selectivity and yield of the reaction, and reduces the occurrence of side reactions. It is one of the great progress in the synthesis of 4-methoxy-2-aminobenzothiazole.
Furthermore, there are also 4-methoxy-2-nitrobenzothiazole as raw material, which is reduced to obtain 4-methoxy-2-aminobenzothiazole. Commonly used reducing agents include iron powder, zinc powder, etc., which are reduced in acidic or neutral media. This approach also provides an effective method for synthesizing the compound. However, attention should be paid to the amount of reducing agent and the post-reaction treatment process to prevent impurities from affecting the purity of the product.
