To prepare 2 - (methylthio) pyridine - 3 - carboxylic acid esters, there are many methods, each with its own advantages and disadvantages. The following common methods are described in detail.
First, the nucleophilic substitution reaction is carried out with 2 - halogenated pyridine - 3 - carboxylic acid ester and methyl mercaptan as raw materials. This is a classic method. The halogen atom of halogenated pyridine has high activity and is easy to interact with the methylmercaptan nucleophilic reagent to form the target product. However, the preparation of halogenated pyridine requires multiple steps, and the cost is high. And the reaction conditions need to be finely regulated. The halogen atom has high activity and is also prone to side reactions, such as elimination reactions, which affect the yield and purity.
Second, the reaction of 2-hydroxypyridine-3-carboxylic acid ester with methyl sulfide reagent. Active methyl sulfide reagents can be selected, such as methyl thiotrifluoromethanesulfonate, etc. This reagent has strong activity and can effectively react with hydroxyl groups to form methyl sulfide substitution products. However, such reagents are often toxic and corrosive, and the operation needs to be cautious, and the price is expensive, which is not conducive to large-scale production.
Third, pyridine-3-carboxylic acid ester is used as the starting material and is catalyzed by metal. For example, metal catalysts such as palladium and copper are used to introduce methionyl into the pyridine ring with the assistance of ligands. Metal catalysts can effectively activate substrates and reagents to improve reaction selectivity and efficiency. However, the high cost of metal catalysts makes it difficult to separate and recover after reaction, which will also increase production costs and environmental pressure.
Fourth, the target molecule is constructed by multi-step reaction using organic synthetic blocks. The fragment containing methyl thio and pyridine ring can be synthesized first, and then reacted to 2 - (methylthio) pyridine-3 - carboxylic acid ester through condensation and cyclization. This method has high flexibility and can modify the structure according to needs. However, the multi-step reaction process is long, the total yield may be low, and each step reaction needs to be strictly controlled, and the operation is complicated.
All synthetic methods have their own advantages and disadvantages. Practical application requires comprehensive consideration of factors such as raw material availability, cost, reaction conditions, yield and purity requirements, and the most suitable method is selected.
