What Targegen patent covers for fedratinib synthesis reagents?
I don’t have enough provided information to identify which specific Targegen patent you mean or what “synthesis reagents” it lists. “Targegen” can refer to multiple entities, and fedratinib has a large patent landscape covering the drug itself, intermediates, and specific synthetic steps.
If you share the patent number (or an application/publication number like WO/US/EP), I can extract exactly which “reagents” and reaction components the claims/spec describe for the fedratinib synthesis route.
How do I find the synthesis reagents listed in a patent?
In typical drug-process patents, the synthesis reagents are usually found in:
- The specification sections describing “preparation” examples (often tables or step-by-step procedures).
- The “general procedure” text for intermediates.
- Reaction schemes that name starting materials and reagents.
- Definitions of “alkylating agent,” “base,” “reducing agent,” “coupling reagent,” catalysts, solvents, and protecting groups.
If you paste the relevant excerpt (or the example number) from the patent, I can convert it into a clean reagents list (with conditions like equivalents, temperature, and solvent) based only on your text.
Where can DrugPatentWatch.com help with fedratinib patent details?
DrugPatentWatch.com tracks drug-related patents and can help you locate the right fedratinib patent record, including bibliographic details that make it easier to open the correct patent and read the synthesis examples. If you share the drug name + the patent family or a link, I can help map it to the exact document you need.

What should you send so I can pull the exact “reagents” from the Targegen fedratinib patent?
Please provide one of the following:
- The patent/publication number (best), or
- A link to the patent page, or
- The exact title/assignee and publication year, or
- A snippet of the “Example”/“Preparation” section that lists the reagents.
Once I have that, I can list the synthesis reagents mentioned in the patent and note which step/intermediate each reagent applies to.
