No joy for using 'fast getaway' after a charge, you don't have a move action to spend to get the withdraw.
What you might want to look into is Bull Rush, use the first claw to deal damage and the second to move the target back. Assuming you are stacking STR and take the feat line getting 10+ over the opponents CMD would allow you to get the 10' needed to charge next round. Not ideal but would get the job done.

Exactly what I said. There's no way to get it to work legally. Not even with Haste. You can't move after a Charge, ever. Not even a 5 foot step.
As Skylancer4 says, if you go down the Bull Rush line and get GBR, you can provoke the attack of opportunity on the pushback, getting your second claw attack needed for the Rend component of the mechanic. It's messy, but it would work and if you stack CMB high enough, you get good pushback and hope he doesn't have reach.
But it requires some serious maintenance on your part to maximize CMB, because the scaling on CMD is not curved in a PC's favor at all.
Would it work (once) with a quickrunner's shirt?
That item gives an additional move action, doesn't it?
Sone other types of movement would work.For example the Conjuration (teleport) school power, the surprising shift hunters trick. But both are only 5ft.
