try:
ip prefix-list DENY-PRIVATE permit 0.0.0.0/0 le 32

you might find http://ws.afnog.org/afnog2012/sie/detail.html to be useful as well.

remember that this just means your router won't listen to bgp announcements for these networks.
that's *not* the same as your network will not trying to send traffic to these;  so hopefully, in addition to not listening to these adverts, (which is good!) you're also filtering traffic *to* those destinations.
