Example:
You told me that the cup had been broken.
I want put 'the cup' before 'You', But it's in a that-clause.
The cup that you told me (that) had been broken is...
Why the 'that' before 'had' have to disappear? What is the correct process to pull out a noun from a that-clause and place it before the main sentence? (Not something like: 'You told me the cup that....')
In your original sentence, "that" introduces a nominal clause. In your second sentence, there is no more nominal clause, so "that" disappears. (Note that in the second sentence, "you told me" is a comment clause, not a nominal clause.) See this recent question, which is very similar: The omission of conjunction 'that' in relative pronoun sentence
There is no single "correct process to pull out a noun from a that-clause". Your idea to use a relative clause and a comment clause is fine:
The cup that you told me had been broken is . . .
If you don't want to use a relative clause, then you could simply put the comment clause at the end:
The cup had been broken, you told me.
