uinolinyl)oxy}ethyl}-6H-dipyrido[3,2-b:2′,3′-e][1,4]diazepin-6-one, (1), labeled with carbon-14 in the quinoline–benzene ring, in one of the pyridine rings of the dipyridodiazepinone tricyclic moiety, and in the side chain, was prepared in three different syntheses with specific activities ranging from 44 to 47 mCi/mmol (1.63–1.75 GBq/mmol). In the first synthesis, 5,11-dihydro-11-ethyl-8-(2-hydro
