What do you know about this reaction? As written, hydrofluoric acid is a catalyst? Or is it in liquid HF as a solvent -- 'cause if that's a real thing ... I don't wanna be the guy doing it.
I also don't see a point of attack for HF, or at l;east, not a situation where HF is what's needed. HF is a common reactant for removal of a silyl protecting group. Could it be its needed later on or before in a chain of reactions and you've put it here by mistake?
