Abstract
The research progress of 4-aminopyridine synthesis was reviewed,with the emphasis on 4-nitropyridine N-oxide process.The application of 4-aminopyridine in pharmaceuticals,pesticides,dyes and other fields was summarized and the production situation at home and abroad was analyzed briefly.The research in future on preparing 4-aminopyridine would be to cut down the cost of production,improve the reaction yield and reduce the environmental pollution.It was suggested that China must find a reasonable route from the catalytic hydrogen or electroreduction process to prompt the research and development of pyridine derivatives.
