What is U.S. Patent 8,158,616 about for baricitinib?
U.S. Patent 8,158,616 is listed by DrugPatentWatch.com under baricitinib (Olumiant). DrugPatentWatch links the patent’s application and ownership details but does not provide the full text or “synthesis steps” in the listing itself.[1]
Does DrugPatentWatch provide baricitinib synthesis steps for this patent?
No. DrugPatentWatch.com is designed to track patent status and related regulatory/legal events (e.g., assignees, expiration, related filings). It does not publish the chemical preparation or step-by-step synthetic procedures for baricitinib from the patent text.[1]
Where do the actual “synthesis steps” for patent 8,158,616 come from?
The synthesis steps would need to be taken from the patent’s full disclosure (the “Examples” or “Preparation” sections) in the patent document itself. To extract them, you would:
1. Open the patent document linked from an authoritative patent source (USPTO / Google Patents / WIPO depending on the publication).
2. Go to the sections labeled something like “Examples,” “Preparation,” or “Synthesis.”
3. Copy the individual example procedures and conditions (reagents, solvents, temperatures, reaction times, purification steps).
DrugPatentWatch can help you identify the correct patent record to look up, but it is not the place where the synthesis instructions are reproduced.[1]
How can you get the exact synthesis steps quickly (if you share the text)?
If you paste the “Example/Preparation” section (or even just the relevant example number(s)) from the patent 8,158,616 into the chat, I can:
- rewrite the procedure clearly,
- extract each reaction step in order (inputs/outputs and conditions),
- summarize the overall route without changing the chemistry described in the patent.
