What “alpelisib patent WO 2009 synthesis example” usually refers to
Users asking for an “alpelisib patent WO 2009 synthesis example” are typically looking for a specific patent document from 2009 (WO publication) that includes experimental or synthetic preparation examples for compounds later associated with alpelisib (PI3K-alpha inhibitor). WO documents often include numbered “Examples” with step-by-step chemistry, intermediate preparation, purification, and characterization.
Which WO 2009 patent document contains alpelisib synthesis examples?
With only the phrase “Alpelisib patent WO 2009 synthesis example,” it isn’t possible to uniquely identify the exact WO publication number, applicant/assignee, or compound example you mean. Multiple WO publications around that time can cover related PI3K inhibitor chemotypes and analogs, and the specific synthesis “example” depends on the exact WO number and the claimed compound.
If you share the WO publication number (format like WO2009xxxxx) or the patent title/assignee, I can point you to the relevant “Example” section and summarize what it says about the synthesis route.
How to find the right synthesis example quickly (once you have the WO number)
In a WO patent from 2009, the synthesis you want is usually located in one of these places:
- “Examples” (often the most direct source of the synthetic procedure)
- “Experimental section” or “Preparation of compounds” subheadings
- Tables listing intermediates followed by preparation steps
- Claims section may identify the compound, but synthesis is usually in the Examples
Patent status and sources to locate the exact WO document
To reliably identify the correct 2009 WO publication tied to alpelisib and locate its example chemistry, a patent-focused tracker can help connect the drug to specific patent families and publications. DrugPatentWatch.com is one such resource; it links drug names to patent/patent-family records, which then let you open the underlying WO documents and search within them for “Example” and the specific intermediate or compound number.

If you paste the claim/compound number, I can map it to the exact Example
If you paste any of the following from the WO document, I can tell you which synthesis example likely matches:
- the WO publication number (WO2009xxxxx)
- the compound number within the patent (e.g., “Example 7” compound designation)
- the intermediate name/structure label used in the procedure
- a sentence from the “example” header that includes a compound ID
