14 C‐Labeled E4010, [4‐(3‐chloro‐4‐methoxybenzyl)amino‐1‐(4‐hydroxy) ‐piperidino]‐6‐[4‐ 14 C]phthalazinecarbonitrile monohydrochloride was synthesized for drug metabolism and pharmacokinetic studies using [1‐chloro‐4‐(3‐chloro‐4‐methoxybenzyl)amino]‐6‐[4‐ 14 C]phthalazinecarbonitrile as the starting material. The radiochemical yield was 33.4%. The specific radioactivity and radiochemical purity, as determined by radio‐HPLC and LSC, were 4.77 MBq/mg and 99.8%, respectively.
