Abstract
Ibrutinib is an oral medication for the treatment of B cell malignancies. During its clinical development, a stable isotopologue of ibrutinib was required for the assessment of the drug's absolute oral bioavailability via intravenous microdosing. The following work describes a 10-step, gram-scale production of carbon-13 labeled ibrutinib from [13C6]phenol (13C6, 99%) in 31% overall yield with >99% chemical purity and >99% enantiomeric excess (ee), suitable for intravenous microdosing in humans.
期刊介绍：
The Journal of Labelled Compounds and Radiopharmaceuticals publishes all aspects of research dealing with labeled compound preparation and applications of these compounds. This includes tracer methods used in medical, pharmacological, biological, biochemical and chemical research in vitro and in vivo.
The Journal of Labelled Compounds and Radiopharmaceuticals devotes particular attention to biomedical research, diagnostic and therapeutic applications of radiopharmaceuticals, covering all stages of development from basic metabolic research and technological development to preclinical and clinical studies based on physically and chemically well characterized molecular structures, coordination compounds and nano-particles.
