Any Cl -or other anions are removed by stirring with a strong cation exchange resin (Amberlite IR-120), filtering, and washing with distilled H2O until the filtrate is free from the anion. The resin is then stirred overnight with 6N NH4OH, filtered, the filtrate is decolourised (charcoal) and evaporated to dryness in a vacuum. The residue is recrystallised from H2O/EtOH. Also crystallise it from aqueous EtOH. The hydrochloride has m 222-224o(dec). [Neelakantan & Hartung J Org Chem 23 967 1958, Connors & Ross J Chem Soc 2119 1960. O’Donnell et al.
