In this article, practical synthesis of a 6,7-disubstituted-1,4-oxazepane intermediate of a compound with peripheral selective noradrenaline reuptake inhibitory activity, in high diastereoselectivity and high optical purity, is reported as an example of drug substance process research (the research was conducted at Pharmaceutical Sciences, Takeda Pharmaceutical Company).
The development of an efficient synthesis method for a novel chiral scaffold, as described in this article, and the technology and experience related to drug substance process R&D is one of the strengths of Spera Pharma . We would like to promote drug discovery R&D by solving customer’s synthesis problems and proposing optimal synthesis methods.
