Beethoven Op 27 No 2 3rd Movement

[svensknavi]

Hello. I'm sure there's been plenty of questions about this piece, and even the particular section I'm stuck on, but I haven't seen any with the problem I'm having. The part I'm having issues with is  bar 32, with the second octave trill. Even ignoring the trill and just doing the octave Fx, I just can't seem to get my pinky to reach far enough to hit the G#. Anyone have any tips? Thanks.

You don't have to hold the bottom note with your thumb.
