摘要

N-(2-oxo-5-phenyl-2,3-dihydro-1H-benzo[e][1,4]diazepin-3-yl) -1H-pyrrole-2-carboxamide-[carboxy- ~(14)C] was prepared as part of a five-step sequence from pyrrol-2-carbonitrile-[cyano- ~(14)C] as a key synthetic intermediate which has been synthesized from 2-bromopyrrole and zinc [~(14)C]-cyanide in the presence of tetrakis (triphenylphosphine) palladium.
