A solution of 2-acetylthio-5-benzyloxycarbonylaminopentanoic acid (1.6 g.) in 2 N hydrobromic acid in acetic acid (10 ml.) is kept at room temperature for thirty minutes. Ether is added to maximum precipitation and the supernatant is decanted. The residue is dissolved in water and applied to a column of Dowex 50 in the hydrogen cycle. The column is washed with water, and 2-acetylthio-5-aminopentanoic acid is eluted with M pyridine-acetic acid buffer pH 6.5.
