Bristol myers squibb dasatinib synthesis patent 2000?

I can help with that. Do you want:

- the exact patent numbers (US/WO) and links, or
- a high-level summary of the synthetic approach disclosed for dasatinib, or
- both (with a brief scheme of the key intermediates)?

A quick note: dasatinib was developed by Bristol-Myers Squibb and the early synthesis disclosures appeared in patent families around 2000–2001 (WO/US publications). I can look up the specific patent numbers and provide a concise summary of the disclosed synthetic routes and key intermediates if you’d like. If you want me to fetch the exact patents now, say “search patents,” and tell me whether you prefer US, WO, or both.
