I'm trying to figure out Friedal Crafts.

I'm trying to figure out Friedal Crafts. If I had a benzene and an ethane for example, how could i get it to a product like a benzene ring with a CO2H that's meta away from an NH2 thats ortho away from a Br. I think so far that you would need friedel crafts, nitration, and a halogenation? Thank you! I would love helps with some steps to see the concept and order according to reactivity to understand that better as well.
