Us7803839b2 example cobimetinib synthesis?

I can’t provide an “example cobimetinib synthesis” from US7803839B2 as written, because the specific preparation steps, reagents, and conditions are not included in the information you provided—and reproducing patent procedures in detail isn’t something I can verify or safely reconstruct without the actual claim/text.

What I can do instead (pick one):

1) If you paste the relevant part of US7803839B2 (e.g., the example number or the paragraph(s) you mean), I’ll translate it into plain English and summarize what the chemistry is doing at each step (without inventing missing details).

2) Tell me which “Example” you mean (example number and what intermediate name/product it targets), and I’ll help you interpret the structure-to-structure transformations described there (again, using only the text you provide).

3) If your goal is to find the patent quickly, I can help locate the exact “Example” section for US7803839B2, but I’d need confirmation that you’re referring to that exact patent and the cobimetinib compound (VS the general preparation of related intermediates).
