What kind are those derivatives? The easiest way of resolution(purification) may depend on their pK, solubility in other solvents, some physical
properties.
If they are easily sublimable, you can probably evaporate the solution to get crystals of HCl salt, add NaOH and heat

Please post one line questions to the short question thread and one line unanswerable questions (those without enough information for an answer) to
the Beginnings section (where I'm moving this).
