If you are allowed to create a static route then try this:
ip route 122.168.1.0 255.255.240.0 Null0
under bgp
network 122.168.1.0 mask 255.255.240.0
neighbor x.x.x.x route-map SUMMARY_ROUTE out
route-map SUMMARY_ROUTE permit 10
match ip prefix-list SUMMARY
ip prefix-list SUMMARY seq 10 permit 122.168.1.0/20
You don't want to use access-list because you will end up matching the
122.168.1.0/24 network.
