Recrystallise the salt by dissolving in EtOH containing a few drops of dry EtOH/HCl, filtering and adding dry Et2O. The solid is dried in a vacuum and stored in a dry and dark atmosphere. It has been recrystallised from EtOH (solubility: 1g in 60mL of boiling EtOH) or MeOH (plates). The free base has b 90-Purification of Biochemicals — Amino Acids and Peptides 100o/0.001mm, 106-108o/5mm and 135-136o/760mm, d 4 1.1559, n D 1.5720.
