Rotate a face

What is the best way to rotate a face from front view to 90°? All I can figure is a series of traditional drawings. I was hoping for some key frame solution, from front to side view. I’m sure I’m grasping at straws, but maybe…

I figured that. Hoping for a miracle, I guess.

Thank you for your quick reply.
