2-pyridinecarboxamide, what are the synthesis methods of 5-amino-
The method of preparing 5-amino-2-pyridineformamide has been explored in the past. One method is to start with 5-nitro-2-pyridineformamide. Take this nitro group, place it in a suitable reaction kettle, add an appropriate amount of solvent, such as alcohol, methanol, ethanol, as the medium. Then add a suitable reducing agent, such as a combination of metal zinc powder and dilute acid, or lithium aluminum hydride, etc., at a mild temperature and stirring rate, the nitro group is gradually reduced to amino group. During the reaction, it is necessary to use suitable monitoring means, such as thin-layer chromatography, to observe its progress. After the reaction is complete, separation and purification, 5-amino-2-pyridineformamide can be obtained.
There is another method to start with 2-chloro-5-nitropyridine. First, the chlorinated nitropyridine reacts with formamide under the catalysis of a base. The base can be selected from potassium carbonate, sodium carbonate, etc., to obtain 5-nitro-2-pyridineformamide. Then, according to the above reduction method, the nitro group is converted into an amino group to complete the preparation of the target product.
There are also those who use 2-pyridinecarboxylic acid as the starting material. First, 2-pyridinecarboxylic acid is reacted with dichlorosulfoxide to form 2-pyridinecarboxylic chloride. Then it is reacted with ammonia to obtain 2-pyridinecarboxylamide. After that, the nitro group is introduced at the 5-position of pyridinecarboxylamide, and the mixed acid (the mixture of nitric acid and sulfuric acid) can be used to control the reaction conditions to achieve nitrification. Finally, as mentioned above, the reduction of 5-nitro to 5-amino can also achieve the synthesis of 5-amino-2-pyridinecarboxylam Each of these methods has advantages and disadvantages, and it is necessary to choose the best one according to the actual situation.
