The key compound ethyl 2,6-dibromopyridine-4-carboxylate was prepared in two steps starting from the commercially available citrazinic acid. By using the Stille coupling reaction ethyl 2,6- dibromopyridine-4-carboxylate was converted to 2,2'-bipyridines, 2,2':6',2''-terpyridines and 2,2':6',2'':6'',2''':6''',2''''- quinquepyridines which bear a carboxylate functional group directly attached to the central pyridine ring.
