If I am seeing this correctly, I think I have found the problem. You are
telling bgp to run using loopback interfaces located on 10.33.1.1/24 and
44.1.1.1/24.
If you do a show ip route, I bet these networks are not in your routing
table and that is why bgp cannot set up the session. You need to do one of
two things. 1) Turn on an IGP to advertise these networks so each router
is aware of the others loopback address OR 2) set up the static routes to
those networks.

Don't know, really. I guess it's just one of those caveats.
Something to bear in mind.
Even in this sample doc, it uses a host route on each router.
