2-Aminopyridine is an organic compound with the formula H2NC5H4N. It is one of three isomeric aminopyridines. It is a colourless solid that is used in the production of the drugs piroxicam, sulfapyridine, tenoxicam, and tripelennamine. It is produced by the reaction of sodium amide with pyridine, the Chichibabin reaction.
Structure
Although 2-hydroxypyridine exists in significant amounts as the pyridone tautomer, the related imine tautomer (HNC5H4NH) is less important for 2-aminopyridine.
