It just takes practice to be honest. You're fingers will eventually be able to do it don't worry. What I used to do was slide that chord up the neck then back down. So you start at the chord you posted then go to

-2---
-2--
-3--
-4--
-x--
-x---

then

-3---
-3---
-4---
-5--
-x---
-x---
ect.

Good luck. Don't worry you'll get it. Don't force it too much either, thats a good way to hurt yourself.
