chemoselective in ester reduction

Hi, I want to reduce an epoxy ester to epoxyalcohol...any idea to reduce selectively de ester and not open the epoxide?
The epoxide contains a bencilic carbon (so reactive)
Thanks

Try DIBAL, it "should" leave the ester intact.
Example:

By which I mean this should leave the epoxide intact, sorry.
