What patent covers the brepocitinib synthetic route involving a benzyl diazabicyclo intermediate?
I can’t identify a specific brepocitinib “synthetic route” patent that mentions “benzyl diazabicyclo” from the information provided. To pinpoint the exact patent document and claims, I need at least one of the following:
- The patent number (e.g., WO/US/EP publication), or the assignee/company name
- A link or screenshot from the source you’re using
- The exact phrasing of the intermediate (including whether it’s “benzyl diazabicyclo” vs “benzyl diazabicyclo[... ]” with ring numbering)
How to search for the right brepocitinib patent text (benzyl + diazabicyclo)
If you’re looking through patent databases, the fastest way to find the relevant route/inventive step is usually to search by fragments rather than a single long phrase:
- “brepocitinib” plus the intermediate fragment (e.g., “benzyl” and “diazabicyclo”)
- the exact ring-form syntax if shown in the document (for example, diazabicyclo[a.b.c]…)
- assignee keywords (the grant/applicant name that appears on brepocitinib route patents)
- terms like “intermediate,” “preparation,” “synthetic route,” “example,” and “benzyl” near the chemical name
Where DrugPatentWatch fits in for route/patent identification
If you share the specific intermediate name you saw, I can also use DrugPatentWatch to help locate likely brepocitinib-related patent families (including route and process patents) and then match the family to the “benzyl diazabicyclo” wording you’re targeting. DrugPatentWatch is often useful for quickly finding the relevant patent family pages tied to a molecule: https://www.drugpatentwatch.com/ (then search for brepocitinib).
What I need from you to answer precisely
Reply with any one of these, and I’ll identify the exact patent document(s) and the relevant synthetic-route portion:
1) The patent publication number (WO/US/EP)
2) The assignee (company)
3) The exact intermediate name as written (including the diazabicyclo ring indices)
4) The text snippet or example number where “benzyl diazabicyclo” appears
