Microwave-promoted syntheses of pyridine carboxamides and tert-carboximides from novel 6-acetylpyridine-2-carboxylic acid

Su, Biyun,Zhao, Jianshe,Zhang, Qunzheng,Qin, Wenlong

experimental part, p. 4429 - 4440 (2010/05/01)

A novel 6-acetylpyridine-2-carboxylic acid (4) was obtained occasionally during the synthesis of asymmetric ethyl 6-acetylpyridine-2-carboxylate (3) from 2,6-dipiclinic acid (1). Compounds 3 and 4 could transform mutually under some specific conditions. T
