What would it take to do this?

I was watching a Turbo 60 on PS the other night and saw the following play that surprised me. I thought it was very interesting, trying to put UTG and the button on the hands they'd need to make these plays (the all-in and the call of the all-in).

Blinds are 75/150

UTG: 6300
Button: 1700
SB: 5250
BB: 250 (100 after posting)

UTG raises to 450, Button raises to 1700 (All-in), SB folds, BB folds, UTG calls.
