You can try the Open Office PDF import extension. Go to the plugin page.
If you just have one or two documents to convert, try freepdfconvert.com - I've used that site with good success (no affiliation). (If you're looking to do this programmatically, I don't know. ).
You can try our product XtremePDFConverter VCL if you can program in Delphi. This VCL component allows intelligent conversion of PDF documents to RTF.
The best I found as an online tool is PDF to Word.
