How thick should a pre-slope be over a Concrete foundation

I am about to make a pan on my first shower, and have a concrete foundation, and the drain was busted out. So I chipped away some concrete foundation to get to drain pipe. I need to know how high to plumb the drain. Specifically, how high do I want my pre-slope to be (How thick) where the pre-slope meets the drain?

1.5 - inch?

thanks in advance
