TīmeklisPyridine is commercially produced by synthesis or by isolation from natural sources such as coal tar. 2-Aminopyridine is manufactured using the reaction of pyridine with sodium amide (Chichibabin amination). It is obtained in high yield after the hydrolysis of the intermediate salt (Merck, 2001; Shimizu et al., 1993). Production/Import Level:
