Abstract
A new method based on the reaction of [2-(bromomethyl)phenyl](4-chlorophenyl)methanone with pyridine-2-amines has been used for the synthesis of 6-(4-chlorophenyl)-11H-pyrido[1,2- b][2,4]benzodiazepin-12-ium salts. The quaternary pyridinium salts, which were formed on the first stage, gave the pyrido[1,2- b][2,4]benzodiazepine system upon heating with acids.
