This is not possible.

If a private key was trivially recoverable based on just a single signature, it would not be a very useful system (such systems do exist, such as IOTA, where keys can be recovered quite easily, but they take other steps to avoid it).

An edge case exists when duplicate r values are used, which does allow for key recovery. Pieter Wuille has an excellent answer detailing how to do that here.
