Take a hacksaw blade with a blade holder and cut down the split in the frame as far down the inside of the seat post as you can go. I have also used a quill stem to grip the post at the top and use that as a pipe wrench to spin it out. Take your time it might take a couple days to loosen this up with the ammonia.
