2-Amino substituted benzothiazoles 2a–l and 2-chloropyridine-3-carboxylic acid 3 were used to prepare 2-[N-(substitutedbenzothiazolyl)amino]pyridine-3-carboxylic acids (4a–l) in 2-ethoxy ethanol. Acid chlorides (5a–l) were condensed with 2-hydroxyethyl piperazine (6) and 2,3-dichloropiperazine (7) to prepare amide derivatives 2-[N-(substituted benzothiazolyl)amino]pyridin-3-yl(4-(2-hydroxyethyl)pi
