Reaction of paractetamol in acidic conditions?

What is the product formed when hydrochloric acid is added to paractetamol?

paracetamol + hcl -> ???

paracetamol + HCl ---> paracetamol hydrochloride
The amine of the parent paracetamol becomes protonated (+ charge) and the Cl- balances the charge.
So, essentially, you have just made the HCl salt of the parent amide.
