The posability of the salts being sulfates have been eliminated via A/B extraction so the only thing that I can think of is that the salts here are
probly norpseudoephedrine and that boiling in the hydrochloric acid gives a 50/50 mix of norpseudoephedrine/norephedrine and the latter being the one
to want.
I wonder why a 25 hour boil in 57% hydriodic acid does not make this change happen yet 32% hydrochloric in a few hours does?
Could it be true that reducing norpseudoephedrine via HI acid only gives the amide and norephedrine give the desired amine? I know this holds true for
the cyanate to 4mar synth.
