On the A321 2700NM with 20t payload seems possible with some margin. Lets assume including reserves it ends up at MTOW
http://www.airbus.com/fileadmin/medi...21-Jun2012.pdf, 3-2-1, page 3.
A321-200 - OEW ~ 106k lbs MTOW 206k lbs.
Payload 44k lbs, so for fuel available ~56k lbs?
Runway length seems also around 2500 m in that case, according to
3-3-1 Page 2
.. although I feel I may have made a little too much assumptions here
Runway length of the 737-900ER at MTOW 174k lbs (which doesn't seem to meet the 2700NM / 200 pax benchmark) seems.. I can't really say for the different temperature, the graph goes very steep there.

What is a little confusing is that Boeing is telling the world the 737-900ER with 204 passengers still flies further then a A321-200 with 184 passengers.
