Hydrochloric acid has marginal solubility in organic solvents (but appreciable solubility in protic solvents such as water). With an amine, however, hydrogen chloride (which in the circumstances would be administered as a gas) would form an ammonium salt according to the reaction:

#HCl(g) + H_2NR(l) rarr Cl^(-)H_3""^(+)NR(s)darr#

Alternatively we could represent the ammonium salt as an #"amine hydrochloride"#, i.e. #RNH_2*HCl#. The ammonium salt would crash out of solution.
