Are you the creator of the document and want to save the original as
greyscale, or you want to convert an already existing PDF?

If the latter I think the easy way is to use ghostscript (pdf2ps) to
render it as greyscale postscript. Then you could convert the PS back
to PDF if you need to. But if you already tried that, then, I don't
know...
