So this is a standard class and not anything you developed? It would have been great if you had mentioned it earlier. Your question was very generic, but as it turns out your are dealing with a very specific problem. It always makes sense to share as much information as possible already in your first post, this way you can save a lot of your time (and others') and improve the chances of getting your question answered.
Also, already in my first reply I asked you to check if your code has main method. So, it's also good to pay a lot of attention to what others write.
Anyway, you might know that only classes that have Main method can be launched via an action menu item. This class doesn't have main method so you can't launch it via a menu item.
But if you look at cross references, you will find how this batch is initialized by Classes\SysCheckListItem_SysParameters:
Here's the code that you can use:
SrsReportRunRdpPreProcessController::createCleanUpBatchJob();
So, if you create a new class that has a main method and put this piece of code in the main method, then you can point your menu item to your new class and set up this batch.
