실험 절차

11.7 g (0.10 mol) D,L-Valine were dissolved in 100 ml of acetic acid and treated with 11.2 g (0.11 mol) acetic anhydride at 90° C. Concentration was carried out after 10 minutes at 15 mbar and 100° C. After HPCL analysis the crystalline residue was shown to contain 95.6% Acetyl-D,L-valine and 2.8% N-Acetyl-D,L-valyl-D,L-valine.
