I'd probably just check the river. More often than not, button will fold to 2BB on the river, but will be much more likely to call for 1BB. A check/call gets 2BB in the river with the button overcall and only costs you 1BB. If you bet out, UTG calls when he's behind and you get an overcall from button, netting you the same 2BB. When you're behind, UTG raises, likely shutting button out and you have to call for the same 2BB, but you lose an extra BB when behind.
