What are the synthesis methods of 2,5-dichloro-4-iodopyridine?

2% 2C5-dihydro-4-pyrimidinone is a class of organic compounds with key biological activities and medicinal value. Its synthesis methods are rich and diverse. The following are common ones:
1. ** Biginelli reaction **: This is a classic synthesis method. Using ethyl acetoacetate, urea (or thiourea) and aromatic aldehyde as raw materials, under the action of acidic catalysts, the target product is formed through condensation reaction. Its advantage is that the raw material is easy to obtain and easy to operate. For example, under the catalysis of concentrated hydrochloric acid or p-toluenesulfonic acid, the product can be efficiently obtained by heating and refluxing in ethanol solution. The reaction process is usually the condensation of aldehyde with urea first, followed by cyclization with ethyl acetoacetate.
2. ** Microwave-assisted synthesis **: With the help of microwave radiation, the reaction process can be accelerated and the reaction efficiency can be improved. On the basis of the traditional Biginelli reaction, the use of microwave radiation can greatly shorten the reaction time and improve the yield. This is because microwave can quickly and uniformly heat the reaction system, promote the enhancement of molecular activity and speed up the reaction rate.
3. ** Ionic liquid catalytic synthesis **: Ionic liquids have unique physical and chemical properties and can be used as green catalysts and solvents. In the synthesis of 2% 2C5-dihydro-4-pyrimidinone, ionic liquids can not only catalyze the reaction, but also improve the selectivity and yield of the reaction. And after the reaction is completed, ionic liquids are easy to separate and recover, and can be reused, which is in line with the concept of green chemistry. ** Multi-component one-pot method **: A variety of raw materials are reacted in the same reaction vessel to synthesize the target product in one step. This method avoids the separation and purification steps of intermediate products, simplifies the operation process, and reduces the generation of waste. If aldehyde, β-ketoate and urea are used as raw materials, in the presence of a suitable catalyst, a one-pot reaction can produce 2% 2C5-dihydro-4-pyrimidinone.
