Question about Haskell AST

I need to be able to take a piece of Haskell source code and get an simplified, typed, intermediate representation of the AST, which means I need to use compiler/coreSyn/CoreSyn.lhs

So I'm first trying to get the desguaredModule of the source code with
        modSum <- getModSummary $ mkModuleName "..."
        p <- parseModule modSum
        t <- typecheckModule p
        d <- desugarModule t

Now I'm really stuck on figuring out how to connect the variable d of type desugaredModule to compiler/coreSyn/CoreSyn.lhs to get Expr patterns like App, Let, Case, etc.

Also, is it correct to get the deguaredModule first?  At least CoreSyn.lhs seems to suggest this.

Any suggestions would be greatly apprecia
