Abstract

Abstract 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) piperazin-1-yl) methanones (8a–l) ...
